5 out of 5 stars. Postcards from Summer by Cynthia Platt is a young adult novel filled with many relatable themes: grief, first love, the innocence of youth, figuring out who you are, navigating family expectations, and the realization that the adults in your life aren’t perfect. The novel is written from the points of view of a mother and daughter when they are both around age 17. In the present, Lexie has always had questions about her mom who passed away when she was a little girl. Her father doesn’t like to talk about her so Lexie has always felt the ache of sadness and curiosity about her. Then, out of the blue Lexie receives a package from the nursing home where her estranged grandmother had been living until her recent passing. Inside, Lexie finds a mosaic chest filled with mementos from her mom’s teenage years. This is how we learn more about Emma’s summers living in scenic Mackinac Island, Michigan. Lexie decides to test the waters of defiance and independence by secretly going to the island in the hopes of learning about her Mom’s past. Throughout this trip Lexie is confronted with more questions than answers… Throughout the novel the reader slowly learns the answers to these questions (as does Lexie, eventually). I found myself anxiously reading chapter after chapter to figure out the answers to these questions. I found some of the characters frustrating at times but one of the highlights of the novel is the character development/growth.. I really enjoyed this novel and give 5 stars.
