From Gretchen McNeil, the author of Ten and Possess, comes this teen horror novel perfect for young fans of Stephen King, and Lois Duncan's I Know What You Did Last Summer.

For Annie Kramer, the summer before college is bittersweet—both a last hurrah of freedom and the last days she'll spend with her boyfriend, Jack, before they head off to different colleges. So she and her friends plan one final adventure: a houseboating trip on Shasta Lake, complete with booze, romance . . . and an off-limits exploration of the notorious Bull Valley Mine.

The legends of mysterious lights and missing persons on Shasta Lake have been a staple of sleepovers and campouts since Annie was a kid. Full of decrepit bridges that lead to nowhere, railroad tunnels that disappear into the mountains, and terrifying stories of unexplained deaths and bodies that were never recovered, Bull Valley Mine is notorious and frightening—perfect for an epic conclusion to their high school lives.

The trip is fun and light—at first. But when a deranged stranger stumbles upon their campsite, spouting terrifying warnings and pleas for help, it's clear that everyone is in danger. And when their exploration of the mine goes horribly wrong, Annie and her friends quickly discover that the menace of Bull Valley Mine doesn't stay at Shasta Lake—it follows them home.

As one by one her friends fall victim to this mysterious and violent force, Annie must do whatever it takes to discover the ancient secrets of the mine and save her friends . . . if she's not already too late.
