Are you ready to journey around the planet to find Dad, a journalist who has been kidnapped? Help Zak and Leah solve the puzzles and save him!

Battle your way through ten scenes and solve the puzzles, from brain-busting maths conundrums to spot-the-difference. Prepare to take a tour through a Machu Picchu maze, go hunting with the Inuits, discover the tallest skyscrapers in the world, dig into a gold mine and explore the Great Wall of China. You'll discover lots about the way people live, work and play around the world. There are search and find challenges on every page.

Puzzle Heroes is an interactive series of very fun, visually-led books containing an adventure or challenge on every page. There are plenty of search-and-find elements in the style of Where's Wally?, combined with topics of educational value, where fun facts help with the challenges. This gives plenty of opportunity to use the book as an extra learning tool - but ultimately the quests are fantastic fun, engrossing readers to the extent that they won't realise they are learning.
