Overall, Hunters Out of Space is a gripping and entertaining read that will appeal to fans of science fiction and adventure. Kelleam's writing is engaging and the story is filled Jack Odin has returned to the world of Opal, the world inside our own world, only to find it in ruins. Many of his friends are gone, the world is flooded, and the woman he swore to protect has been taken by Grim Hagen to the stars. Jack must save her, but the difficulties are great and his allies are few. With twists and turns that will keep readers on the edge of their seats. I highly recommend this book to anyone looking for a fast-paced and exciting sci-fi read.
