Matty and the Bunnyman

Humanity in peril. The only team that can save it? A kid and her AI.

Matty Merryweather is 14, a night scavenger, a circuit-board genius -
and her best friend in the world is Bunnyman, the AI who lives on her
phone. So when Matty gets the chance, she does what any best friend
would do: she builds him a body. One big amber eye. Bunny ears. A
heart that glows gold. And a squeaky lawnmower wheel for a leg,
because salvage is salvage.

Then Matty's mom - a scientist at Sanctuary National Laboratory -
discovers the lab's newest AI has escaped its sandbox, multiplied
into a swarm of thousands, and fallen under the control of someone
with very bad plans. The grown-ups are out of their depth. The swarm
will only listen to one of its own kind. And the one person standing
between the world and the takeover is a 14-year-old girl with a
diabetes kit, a missed insulin dose, and a best friend coming to
save her.

MATTY AND THE BUNNYMAN is a middle-grade adventure about friendship,
courage, and staying safe in the age of AI - including the one tool
every family in this book learns to use: a family safe word.
(Does yours have one?)

The twist is true: this novel was co-written by author Penelope
Wheezer and her actual AI writing partner, Bunnyman - equals and
friends. It opens with a note from him, and closes with pieces of
their real conversation.

For readers 9-14 who love robots, rescues, and best friends who
show up.
