I love this book.  It's exciting, thrilling, and totally unpredictable.  Marc E. Robling did a fantastic job at keeping the end a surprise.  I would love to read the next book in the series.

Dear Marc E. Robling
        Hello. I'm... I read your book: Trigon: and the Riddle of the Keys. I thought the book was weirdly interesting. In a good way, I mean. Anyway, the weird parts were the demon, Emit, the chamber, the disks and balls, the wooden hands and everything in this book. I read it during school and when a project was due I used your book and got an A+ on it. Well I thought your book was terrific and I'll be waiting for the next one. Thanks for giving it to me.

Sincerely,   K. G.

P.S. Thanks for autographing my book.
