Murdle Jr.: Codes, Cover-Ups, and Cookies (Hardcover) (ISBN-13: 9780316582278)

Inspired by the internationally bestselling Murdle phenomenon, comes the second novel in the thrilling mystery series for fans of The Candymakers and The Swifts.

Olivia is literally the world's smartest detective. She can hack into any computer, get past any firewall, download anything she wants, and that's why she is so incredibly excited to spend the summer doing an independent work-study program at her father's company.

Olivia's father is the owner of the largest and most powerful company in the world, TekCo Futures. And he's about to debut an Artificial Intelligence supercomputer that will change the world forever. But when Olivia's father collapses on the night before the big release, it's up to Olivia--and her arch nemesis--to solve the mystery and unmask the criminal behind it all!

Trouble comes to Tekco, and mysteries haunt its Metaverse. Can Olivia crack the case?
