The Sorta Sisters — Adrian Fogelin

Anna and Mica live totally different lives on either end of Florida, but a chance correspondence begins a friendship that helps both girls to face the uncertainties and fears in their lives.
Anna Casey likes living in North Florida with her latest foster mother, but it is hard growing into a new family and way of life, especially when you've been rootless nearly all of your life. Mica Delano likes living aboard her sailboat at a marina in the Florida Keys, but Mica fears that her restless father will soon pull anchor, taking them away from the safety of the familiar marina.
A chance correspondence between these two girls becomes a flourishing friendship. As they share their love of nature, each helps the other cope with uncertainty, loneliness, and profound change. Mica enrolls in public school for the first time since first grade, and Anna must make room in her heart when her beloved foster mother becomes serious about a suitor. In the end, Anna and Mica save each other and themselves with hope, humor, and a shared love of the natural world.
Award-winning author Adrian Fogelin's latest book for middle readers follows an unlikely but enduring friendship that is forged between two adolescent girls.
