In 1998, Elsa Jorgenson suddenly disappears during a road trip with her daughters, Lily and Iris, in Australia. Iris also vanishes briefly, but returns, and the girls begin a tumultuous journey without their mother, who has completely vanished. Twenty-four years later, Lily returns to Australia, determined to get answers. She will start with her estranged sister, Iris, for Lily is convinced Iris is keeping secrets.

Birds in Flight is a compelling and nuanced mystery that will keep you guessing. The secrets and revelations are riveting. Among the serious issues discussed are mental health, depression, abuse, abandonment, and cult-like behavior. This book is so richly layered, and as each layer is lifted, more of an absolutely intriguing mystery is revealed. It's a dynamic story of family secrets and the quest to finally solve them. It's also a road trip book in more ways than one, as Lily and Iris retrace their mother's footsteps and learn her life story.

I had a hard time putting this mystery/adventure down, and the conclusion is clever, heartbreaking, and unexpected. I would recommend this book to anyone who wants to read a complex mystery that explores family dynamics. This is a story you won't soon forget.
