Start Here, by Trish Doller

Willa, Taylor, and Finley were supposed to take a grand boat trip together from Ohio to Key West after high school graduation, but then Finley succumbed to her leukemia and didn't make it.  But they still have the boat and a list of clues Finley created for them to solve on the route. 

Neither one of them is truly enthusiastic about taking the trip.  Finley was the glue that bonded the three of them together.  In her absence, Willa and Taylor aren't really close enough to survive close quarters and 2000 nautical miles.  But their loyalty to their late friend and a shared desire to honor her drive them on.  And during their coastal road trip they survive threats both emotional and physical, find love, discover themselves, and come to terms with life after Finley.

No literary masterpiece, but a nice solid road trip story with an unusual setting.  Knowing just about nothing about sailboats, there was just enough detail here to entertain me.  Great characters and some fun lighthearted romances gave me something to enjoy.  Finally, just enough adventure to explain the transformations and growth that I basically was craving for.
