Bigfoot! (Mysterious Monsters Book 1)
The Mattigan kids don’t believe in things that go bump in the night. After all, their dad is famous for proving such things are impossible. But when their long-lost Grandpa Joe shows up with his Mysterious Monster journal begging for help, the siblings find themselves drawn into a search for Bigfoot. Along the way, they’ll have to deal with meddling babysitters, suspicious psychics, a youtube disaster, and their furious father. To solve this mystery, Maddie, Max, and Theo will have to rethink what’s possible — and make lots of peanut butter and banana sandwiches.
