Rick Riordan

It's always hard to wrap up a series. The longer I spend with the characters, the more they become like friends.

It is true that I once refused to eat haggis in Scotland and this did not sit well with the local population.

I saw 'The 39 Clues' as a potential vehicle for doing some education in a fun way - to take some of these amazing stories from history, dust them off and make them alive.

It's good to like yourself, and that only comes from hard work, from doing. But vanity is dangerous; it can trip you badly.

Another thing that freaks me out is time. Time is like a book. You have a beginning, a middle and an end. It's just a cycle.

It took me realizing that a broken heart has never actually killed anyone to find the courage to ask for what I want, in just about every situation. That was part of my own growing up.
