I am a huge fan of this crazy actor both from his roles when he was young such as in Doogie Howser MD or as he got older in How I Met Your Mother.
This is just another aspect of this oddity. He has a lot of talent and writing middle grade or young adult books just seems to suit him so well.
I find that he has great ability to write a story that you just can’t stop reading. It held so many secret treasures that you can’t help but fall for it and I really can’t wait to get into his further adventures of the misfits.
