Not Again (Mountain to Coast Romance - Book 3) by Ann Tonnell

Sixty something Sam Avery has sworn off new relationships.
Surrounded by supportive friends, she focuses on a cycling trip along
the east coast. The ride should center her and honor the memory of the
love of her life, whose dream was to be riding also. Avid long-distance
cyclist, Lee Floyd, is invited to sub for the missing Deb and sets her
hopes in Sam. While Sam gives Lee no encouragement, she is pulled in as
a nurse helper when Lee’s health takes a turn. Will this necessitated
closeness give Lee’s desires a chance? Or will Sam remain steadfast in
her determination to find her happily ever after in the company of
friends? Something unexpected happens when a chance encounter literally
knocks her off her feet.

From the author of How Sweet the Sound, Not Sorry, and Not Too Old, this is Ann Tonnell’s third  Mountains to Coast Romance.
