A Love Story Starring My Dead Best Friend

Cassie is in grief over the death of her best friend, Julia, who died behind the wheel in a road accident. She had unrequited romantic feelings for her friend, and now she is determined to cycle from Illinois to California with Julia's ashes, so she can scatter them in the ocean that Julia never managed to see.
Over the course of her trip, through various experiences and encounters, Cassie confirms to herself that she is gay. And then, when her bike and most of her money is stolen, she discovers her true friends and a sort of unhoped-for salvation.
Interspersed through the narrative is the unfolding love story between Heather and Cassie, as Heather slowly reveals to Cassie her true feelings, and Cassie begins to open up to the possibility of reciprocal romance.
