When Sierra sneaks out, determined to escape her over-protective family, she stumbles across a young man covered in blood. His last words are a plea. Find the Grail Keepers. Warn them.

Ryder is the young cop who was last seen with the murdered victim. Sierra doesn't trust him, no matter how drawn she is to him. Except it turns out they're both looking for the same thing—the Holy Grail.

They're quickly drawn into a dangerous hunt involving cryptic clues, a mysterious stone, and a Grail that hasn't been seen for centuries. One that leads to more questions than answers. Can Sierra trust her impulsive emotions? Should she believe Ryder's words or the truth she sees in his eyes? And ultimately, should she follow her heart?

Especially when every decision will decide the fate of countless lives.
