Are Darkhounds really magically mutated Dog Boys? Is that why they see Coalition soldiers as friends and allies? Ee-Bee Gee-Bees are kinda cute, how dangerous can they be? Is it true the animals and people slain by the Death Springer rise as zombies?! What on Rifts Earth is a Field Reaper? This book reveals it all.
