The Other Family by Loretta Nyhan

Ally is desperate to help her daughter, Kylie, who has an autoimmune disorder. Ally decides to do a DNA test to see if the results will help them discover if there is an unknown health issue that could be causing Kylie's problems. Ally had a great childhood with her adopted mother, Sophie, who brought Kylie and Ally into her home after Ally's separation from her husband, Matt. Sophie, however, is not happy about Ally's decision to take the test, feeling threatened about Ally possibly having a relationship with her birth family. When Ally does find them, will it enrich her life or cause more pain? If you enjoy novels about relationships and are looking for a new author, give this one a try.
