The first book I read for the FFP 24-Hour Readathon was Vespers Rising, book #11 of the 39 Clues series, which I was reading for the launch party organized by Scholastic Philippines and National Book Store the next day.
I was eager to read this book after I finished book 10, Into the Gauntlet by Margaret Peterson Haddix, because I wanted to see Dan and Amy return for their next adventure! I originally thought Vespers Rising was the first book in the second 39 Clues series, but it turns out it’s actually the “bridge book” that links the two parts together.
