Grandfather Crypto Launch

Grandfather Crypto, book five in the Old Code series, is now out in the world!

Ajay Andersen broke cryptography, but there are still plenty of secrets.

A work of art is stolen from the Minneapolis Arts Institute, but there’s something strange about this modern Russian masterpiece. It’s both a callback to a simpler time and a step forward into the future. Its value is not in provenance or materials. It’s in knowledge.

And someone’s desperate to learn the truth.

When the thieves ask Ajay to solve this unsolvable puzzle, he needs to decide what he cares about more: staying hidden or staying safe.

This was a fun book to write, and I hope people enjoy it as much as I do. This book marks an interesting transition for Ajay and Kylie, and I hope you’ll be along for the ride. The world’s getting more dangerous for the girls with their powers, and the world is getting harder for the old man to hack. Something’s got to give.

You can, of course, grab a copy of the book here in the store or basically anywhere books are sold.
