Every summer, Samantha Wheland joins her childhood friends --- Isabel, Kendra, Mina --- on a vacation, somewhere exotic and fabulous. Together with their mixed bag of parents, they’ve created a lifetime of memories. This year it's a beach house in Honduras. But for the first time, their clan is not complete. Mina lost her battle against cancer six months ago, and the friends she left behind are still struggling to find their way forward without her.

For Samantha, the vacation just feels wrong without Mina. Despite being surrounded by her friends --- the closest thing she has to family --- Mina’s death has left her a little lost. Unsure what direction her life should take. Fearful that whatever decision she makes about her wealthy French boyfriend's surprise proposal, it'll be the wrong one.

The answers aren't in the journal Mina gave Sam before she died. Or in the messages Sam believes Mina is sending as guideposts. Before the trip ends, the bonds of friendship with her living friends, the older generation's stories of love and loss, and Sam's glimpse into a world far removed from the one in which she belongs will convince her to trust her heart. And follow it.
