My son read 'The Looking Glass Wars' the first book in the series by Frank Beddor.  He wants books 2 and 3 in the series, so they are on my WL.  In my search, I found another book, called, 'Hatter M: The Looking Glass Wars, Vol 1' and 'Hatter M, Vol 2: Mad With Wonder'.  Are these books by the same author, and kind of from the same series, but from a different character's point of view?

I am pretty sure those are graphic novels from a different author. I have the Looking Glass Wars trilogy and have never seen any other books in the series.

I have read all of those books, so I am familiar with them all.  The original trilogy books are The Looking Glass Wars, Seeing Redd, and Archenemy. 

The Hatter M books are what you would call a "spinoff" series.  They are in graphic novel (comic) format.  I believe Frank Beddor worked on the series, but employed a comic writer/artist.  They from the point of view of one of the characters, Hatter Madigan, from the main books, and take place kind of in the middle of book 1 chronologically (after Alyss leaves Wonderland, but before Hatter finds her again).  The Hatter M books are about the adventures Hatter has while he is searching for Alyss. 

Thanks!
