Twelve-year-old Byrd has no real identity. She's known as the girl watching from the outside of Mr. Godwin's sixth grade window, writing equations down on her forearm with a sharpie found in the mall bathrooms. A smart girl, and a sweet girl, but no one gives her enough time to realize it. Being part of a dysfunctional family where everyone is called by their title, Sissy, Bubby, Mommy, and Daddy living in an old trailor park called home classifies you in the rank with all the misfits.
But one night when her family is sound asleep Byrd leaves. The creaking of the old ragtag door awaking Sissy, the glinting of the stud in her tongue shining in the distance as the police cars arrive. Little do they know where she's hiding, squeezed into the old stone bridge's gap. With no idea where she is heading, Byrd carries on, soon the Asveils find her. After being brought to the Asveils Orphanage, everything that she has ever wished for comes true.
Though after a series of events, Byrd realizes maybe she was ment to stay in the Oakly Trailor Park with her unstable family. Befriending two girls on the way back home, Hadley and Alistair, returning to Salem might not be the easiest thing to do. The police just one step behind, planning to introduce her new 'sisters' to the rest of the family, and picking up an old hound dog is the recipe for The Byrd Who Flew.
