The Immortal - (Rise of the Warlords) by Gena Showalter

The Immortal is a thrilling and captivating tale of an assassin and a warrior, trapped in a time loop with no escape.

Halo Phaninon, a cold and merciless killer, is tasked with killing 12 mythological monsters in 24 hours, but each morning he awakens to the same day, reliving new horrors.

The only person who retains their memory is Ophelia the Flunk Out, a beauty who threatens his iron control.

As they repeat their doomed cycle, Halo's desire for Ophelia grows, and he will stop at nothing to save her...and lure her to his bed.

But if he escapes, they will lose each other forever.

Will they find a way out of the time loop, or will they be trapped forever? The Immortal is a must-read for fans of dark and sexy fantasy, with a unique twist on the classic "trapped in a time loop" trope.
