Karen recently enjoyed A Secret Shared by Patricia MacLachlan, a "sweet family story" about adoption for school-age kids. 

"A Secret Shared is a sweet family story about adoption and what it really means to be family, suitable for younger to middle grades. Nora and Ben are twins who accidentally discover that their little sister is adopted. Birdy likes to keep secrets, and when their mother was sending off a DNA kit for discovering your ancestry, she also spit in a vial and sent if off without anybody knowing. When it comes back showing totally different origins than the rest of the family, the twins are baffled and start to investigate and uncover their parents’ secrets and find out how Birdy came to be part of their family."
