The title of the book is exactly what you think it's about-zombie dinosaurs! Alex Ramirez is an environmental activist who goes after an Antarctic research team. What this team is doing is uncovering frozen dinosaurs, a giant T-Rex among them. You see, it wasn't an asteroid that killed off the dinosaurs-it was a zombie virus that made them eat each other. Alex first encounters a Russian expedition group that's been contaminated-not only are the "undead" but they have reptilian skin and eyes. Things get complicated once he's captured by the research team. It's funded by an insane rich guy who wants to weaponize the virus and sell it to the highest bidder. Also involved is an undercover woman government agent, who is out for revenge, and Alex's father, who is working for the madman.
JURASSIC DEAD is a fun read, giving you exactly what you expect, including an exploding volcano at the end. Recommended.
