Black Horse — Connie Myres

The third seal of the Book of Revelation opens, forcing famine upon the ragtag characters as they deal with aliens and dinosaurs inside the planet of Mars.

(Book 3) Sarah, Jack, Max, Willis, Georgie, Miss Foo, Father Mitch, and prepper Randy are captured by the half-breeds and are to be fed to the alien bioship. While onboard the spaceship, they end up inside Mars where dinosaurs from the Mesozoic Era roam and creatures are jailed. 

However, to get back to Earth they need to rescue an ISS astronaut, Ray Barber, from the reptilian corral so that he can fly the Pegasus capsule when they return to Earth orbit. To accomplish this, they must avoid being eaten by dinosaurs, survive a waterfall, and fight alien creatures, all while Randy shows signs of double-crossing them. If they manage to rescue the astronaut before the bioship leaves, they just might make it home. 

Suspenseful, optimistic, and awash in Prehistoric and Egyptian symbolism, this apocalyptic series continues to follow its ragtag characters as the third seal of the Book of Revelation opens.
