Rhapsody (Hearts of Heroes - Book 4) by Molly J. Bragg

Megan Harwood never wanted to be a hero. She just wanted to indulge the two great loves of her life, woodworking and music, and for the last few years, she’s done just that running a small guitar making business in Sun City Florida with her dad’s help. But when Megan refuses to sell her shop, she ends up on the hit list of the Unitarium, an organized crime syndicate made of up supervillains and their minions. After being grabbed off the street and used as a test subject in one of their experiments, Megan begins hearing a woman’s voice in her head. A voice that turns out to be Eurion, the beautiful woman Megan has had a crush on for the past year. A woman who also claims to be an ancient red dragon. With Eurion’s guidance, Megan is able to escape from the Unitarium’s clutches, and in the process, she discovers that they have infiltrated the Department of Metahuman Affairs. Before Megan can decide who to trust, she finds herself framed for Eurion’s murder, putting her squarely in the crosshairs of some of the world’s most powerful Superheroes. Frightened, alone, with only the voice in her head for guidance, Megan has to find a way to rescue Eurion and clear her name, before Eurion’s friends hunt her down.

Sean, a mercenary, is the bodyguard of Grand Master Caila of the Order of the Paladins of the Republic. A fact that the entire Order, except for Caila herself, resents deeply since they kicked Sean out almost twenty years earlier. It doesn’t help matters that Caila has taken a vow of Celibacy, but everyone knows that she and Sean have feelings for each other. Sean’s presence is only tolerated because Caila is the official Seer of the Paladin Order. While all Paladins can see the future to a limited extent, Caila’s gift with foresight exceeds even the head of the order. But when a mine destroys Caila’s ship just as they arrive in the Ptolemy system to settle a dispute over a hyperspace route, it quickly becomes clear that someone doesn’t want their mission to succeed. With only Reagan, a Paladin with a personal grudge against Sean for support, Sean and Caila make their way to Ptolemy, recruiting allies along the way. But each time they look into the future, Caila sees a vision showing her that Ptolemy will be reduced to a lifeless cinder if they leave, and Sean receives a warning that Caila will die if they stay. Can they avoid disaster, or will Caila be forced to sacrifice herself to save an entire world?

When Deputy US Marshal Danielle 'Danny' Martin was told she'd gotten a promotion, she expected to be leading her own fugitive retrieval team.  Instead, she got transferred to Pontian Florida of all places, and assigned to a Superhero support detail for Focus, a seemingly immortal superhero who is also one of the most famous lesbian icons on the planet. Bad enough she's got to spend every day working with a woman she's had a crush on since she was five years old, but when she arrives at her new post, things start getting weird.  It turns out that Focus asked for her by name, and it quickly becomes apparent that Focus wants to be more than just coworkers, or even friends. After Focus has a violent reaction to Danny getting hurt in the line of duty, she starts looking into why the Superhero might be so fixated on her.  She begins to suspect that seeing the future might be one of Focus' powers, but when a mission leaves her stranded thirty years in the past, right at the start of Focus's superhero career, everything becomes clear, except why the Focus in the past can barely seem to tolerate her presence.

When Maggie Bennett agreed to take a break from her own research to be the test subject in an experiment, all she wanted to do was help her best friend Sierra secure grant funding for the new medical imaging machine she was developing.  But when Sierra’s ex-boyfriend Garrett causes an explosion in the lab next door, Maggie finds herself gifted with Superpowers and in the custody of the High Guard, Sun City’s most prominent Superhero Team. At first, it isn’t bad.  The High Guard is helping her learn to use her powers while also working to keep her and Sierra from getting blamed for the explosion.  And there’s Varsha, the cute speedster that keeps showing up at her room with homemade ice cream and staying for lesbian movie marathons.  But when another series of explosions at the school where Maggie and Sierra work reveal that Garrett didn’t die in the accident that gave Maggie her powers and is part of a plot to reverse engineer banned alien technology with ties to her past, she finds herself pushed into the role of a reluctant Superhero. Caught in a race against time, Maggie must master her new abilities, and use her skills as a scientist to figure out why Garrett and his accomplices want the technology - and who they intend to sell it to.

She expects the mission to be like any other.  Get in, eliminate the target and get out again.  Instead, when she arrives, she finds out that one of the leaders of the fascist Char Oram is there, seeking to turn the inhabitants into mindless soldiers that could tip the war in favor of the Char.

When Naomi Woodward's doctor recommended her for a clinical trial, it seemed like the answer to her prayers.  She was finally able to get her gender confirmation surgery and the surgery was a resounding success.  She finally looked and felt like the woman she always knew she was. Her new face and new body finally helped her work up the nerve to ask out Anika, the beautiful nurse that lived across the hall.  To her delight Anika said yes, but when they are attacked during their date, Naomi quickly discovers that the experimental procedure she went through had some unexpected side effects, and that when Anika told her things with her family were complicated, she really should have listened. Now, armed with superpowers she barely understands, a snarky artificial intelligence in her head, and allies that include a Superhero, a Dragon, and the literal Devil, she has to keep Anika safe from the archangel who's out to kill her while they work desperately to prevent a second civil war in heaven.
