This series is so engaging, compelling, and exciting! You can barely put the book down at night! It has scary confrontations with monsters, yet there's usually some funny commentary. You feel like you meet friends and are right there with them on all of their harrowing adventures. The best part is how they learn to appreciate each other, work together, and trust each other with their lives. It's a wonderful message to young readers. And the author develops each of the main characters with memorable, unique personalities! I started reading this series with my 10-yr old grandson so we could discuss the story together and then got hooked! Now both my husband and I are two 60-somethings loving these books!!
