Echo Dominion - Echo Power Trilogy, #2

The apocalypse has reawakened-and it wants blood. The Echo devoured our world, then slept for months. But now its convulsions threaten to destroy the safe little community I and my fellow survivors have built in an untouched wilderness. I can't let that happen. Maybe it's the cop in me or the Army veteran in me, but I need to take action. By going inside the parallel world known as the Echo. A hell full of ravenous beasts. I can't do it alone, though.
And the only person I'll risk taking with me is Erin Harding, a former Marine who's also a loose cannon. The fact that I'm attracted to her only makes our mission more dangerous. Because I can barely restrain my lust for Erin. But I will never let her know that. To save Earth, we must penetrate the heart of the Echo and somehow seize control of it. Piece of cake. It's not like we have no idea how to do that. Yeah, we're all screwed. Echo Dominion is the second book in the Echo Power Trilogy of dark, steamy paranormal romances.
