Can you ever go back, make up for lost time?

After finding secreted love-letters inside an old wall during a home renovation, genealogist Ellie McLellan is back in action—still juggling her own demons, of course—while tracking down another mystery, a mystery with the power to destroy a family.

Before Ellie has even started to investigate, her client Ruth appears on her front porch, incoherent and soaked to the skin, clutching the discovered letters. Driven to learn the truth herself, Ruth found concealed diaries in her dusty attic. Diaries kept by the person she trusted most in the world—and is shocked to realize she's been living a lie.

Taking Ruth in, Ellie begins a seemingly impossible search with the help of her weekly genealogy group.

Can Ellie solve the decades old mystery for Ruth?

Can Ruth's family survive this heart-breaking betrayal?

More important—can Ruth catch a falling star before it's gone for good?
