Due to a flash flood and a fender bender, Ava Granados missed her grandmother's mystical blessing, one that has been passed between the women of her family upon death for generations. Turns out, Nana did give Ava a blessing, but it missed its target, landing with the boy driving the other car in the accident. Now Nana's ghost challenges Ava to reclaim her share of the family magic--and set Nana free. As Ava embarks on her mission to retrieve the lost blessing, she starts to wonder if getting close to thunderstorm boy is worth the risk of getting close to someone she could have feelings for. -- Adapted from front book jacket flap.
