First Line Fridays is a weekly feature over at Wandering Words where you put the first few lines of a book in order to get your readers hooked, then show them which book it is!

This week’s first lines are:

At exactly ten o’clock on Saturday morning the doorbell rang, and I knew it would be Harriet because she was never a minute late. I emerged from the bathroom, still in my pajamas, as the bell sounded a second time. Flicking back the curtains to be sure it was her, I saw Harriet hovering on the doorstep, her arm tightly gripped around her daughter’s shoulders. Her head was hung low as she spoke to Alice. The little girl beside her nodded as she turned and nestled her head into her mother’s waist.

Do you recognize those lines?

They’re from Her One Mistake by Heidi Perks! Did you get it?

Summary:

What should have been a fun-filled, carefree day takes a tragic turn for the worse for one mother when her best friend’s child goes missing in this suspenseful, compulsively readable, and darkly twisted psychological thriller.

It all started at the school fair…

Charlotte was supposed to be looking after the children, and she swears she was. She only took her eyes off of them for one second. But when her three kids are all safe and sound at the school fair, and Alice, her best friend Harriet’s daughter, is nowhere to be found, Charlotte panics. Frantically searching everywhere, Charlotte knows she must find the courage to tell Harriet that her beloved only child is missing. And admit that she has only herself to blame.

Harriet, devastated by this unthinkable, unbearable loss, can no longer bring herself to speak to Charlotte again, much less trust her. Now more isolated than ever and struggling to keep her marriage afloat, Harriet believes nothing and no one. But as the police bear down on both women trying to piece together the puzzle of what happened to this little girl, dark secrets begin to surface—and Harriet discovers that confiding in Charlotte again may be the only thing that will reunite her with her daughter….
