Kaiju World by R.F. Blackstone

Kaiju World is going to be the greatest theme park the world has ever seen. Gideon Pryke, the owner, has amassed a collection of city destroying monsters. The park will offer the world the chance to get up close, have a photo taken with and fight a Kaiju with a giant mech!

With only two weeks left until the grand opening the world watches the tiny island off the coast of Japan. But when a team of Animal Activists release the monsters death and destruction ensue. They and the staff of Kaiju World will learn that sometimes bigger isn't better.
