Ru Roberts has finally accepted her fate as a Keeper—a half-angel bound to banish Grim Reapers back to Hell. Now comes the ultimate test: locate and seal the three remaining portals to Hell, trapping the Reapers on Earth where they can be permanently destroyed. The challenge is monumental. Ru possesses the will to succeed, but does she have the power? Finding the portals proves daunting enough, but closing them demands extraordinary strength she's unsure she possesses. Her mission grows darker when Thanatos emerges as her greatest adversary. The most formidable Reaper alive and son of Azrael—the demon commanding all Reapers—Thanatos has his own agenda: her death. With the demon lord's heir relentlessly hunting her, Ru must balance the race against time with the deadly threat at her heels. Every choice brings her closer to triumph or annihilation. Can Ru discover the portals and seal them before Thanatos claims her life? The fate of both worlds hangs in the balance. Ruin's Legacy concludes the Reaper's Hollow trilogy.
