A young girl attacked. An unbreakable pact. There's more in the woods than meets the eye.

When 13-year-old Eliza Loft learns that high school senior, Renée Pope, was brutally attacked and killed, she's horrified-and she just might be the only one who knows what happened. After all, Eliza was in the woods that night, and what she saw haunts her for years, especially since she can't talk about it with anyone. Not when she knows deep down that a moment of mischief between friends might have been a contributing factor in Renée's death.

But when an anonymous note claiming to know all about her involvement appears in Eliza's locker years later, staying quiet about what happened may no longer be an option. After a co-conspirator with shared responsibility for the prank that led to Renée's death receives an identical message and turns up dead just one day later, Eliza becomes even more panicked. Suddenly, she's convinced that she's being targeted for what she did and must fight to prove what happened before it's too late.

A twisty, unpredictable thriller full of dynamic characters and dark secrets, I Know What I Saw is a gripping coming-of-age story that seamlessly blends elements of paranormal folklore and sasquatch mythology with all the conventions of a spellbinding whodunnit.
