#1 New York Times bestselling author Margaret Stohl and Lewis Peterson’s hilarious middle grade debut has it all: robot overlords, secret feline agents, and earthling humans who are in for a real catastrophe.

With examples of why coding is fun and other STEM applications cleverly woven into this fun and thoughtful story about looking beyond binary terms, this is the perfect novel for fans of House of Robots and The Tapper Twins. This middle grade novel is an excellent choice for tween readers in grades 5 to 6, especially during homeschooling. It’s a fun way to keep your child entertained and engaged while not in the classroom.

The Robot Federation and the Feline Empire have been at war for eons. And now that fight is coming to a tiny primitive planetoid…Earth. The mission for both cats and robots: retrieve the Singularity Chip. With it, cats can live past their nine lives, and robots are granted eternal battery life.

Meanwhile, twin siblings Max and Min Wengrod are as different as can be. Min always gets good grades, and she loves to read and build robots. Max hates school, and prefers to play games and spend time online with friends.

When Max rescues two kittens and is determined to keep them, Min is horrified that these furballs could ruin her chances at the Battle of the Bots competition. But with hidden forces at play in their own house, and the larger war between cats and robots  fast approaching, will the twins be able to put aside their differences before they get caught in the crossfire?

“While comically contrasting the vast gulf between the mentalities of machines and cats, and (plainly) having great fun with names, the authors also work in significant gulf-bridging elements and developments. A STEM-friendly, high-interest adventure.” — Booklist
