Nine-year-old Penny Jones and her corgi sidekick, Luck, thought their summer would be ordinary – until a twist of magic sends them tumbling into a whole new world! BOOYAH!

Penny and Luck’s summer plans did not include finding a secret portal in their garden or being whisked away to a magical forest, where bicycles fly and birds are as big as watermelons! But trouble is stirring, and a warrior princess needs their help to save her home from the evil Shadows...

As secrets are revealed, Penny soon discovers that there is more to this enchanting place than meets the eye. Can she use her inventing skills to help the princess AND get back home before time runs out?

Perfect for fans of the thrilling adventures and daring rescues of Philip Reeve’s AdventureMice series, combined with the humour, heart, and quirky world of Sophy Henn's Pizazz series, Claire Karwowski’s debut is a whirlwind story of magic, bravery, ingenuous inventions, and a whole lot of BOOYAH.
