When she hears that the residents of Aviles know how to communicate with loved ones who have died, she knows she has to go - if she can contact her mother, she might have all the answers she needs. For generations, Leo Mercury's family has been in charge of the Aviles Island lighthouse. Now, his family runs the annual Tidings Festival, when everyone in town can trade letters with loved ones who have died. When nosy Alice Jones shows up for the festival, Leo knows it's up to him to protect the island's traditions. Because something about the tidings is changing, and he needs to fix it before it's too late. Between the Lighthouse and You is a heartwarming story about love, grief, and letting go.
