The Leavers by Lisa Ko
Warning: sure to cause tears for every mother on this planet. An undocumented Chinese immigrant goes to work her shift at a nail salon but disappears without a trace . . . the heartbreaking caveat? Her son Deming Guo is left behind and later adopted by two professors. A vivid portrait of a mother's love and a directionless boy trying to find himself without the anchor of his mother, The Leavers is one of this Summer's most emotional and inspiring reading events.
