Found: YA Graphic Novel Flames on Cover animals in space suits

My son is looking for a book he once saw and can't remember. The cover had a lot of fire on the cover, the title was in the middle, there might have been a purple jewel, and there were animals in spacesuits on the top and a warrior girl on the bottom. He remembers it had a purple monster in it who had no eyes but had a jewel in the center of its head. Any help here would be TREMENDOUS!

It was a series, and the first one was grey with gears on it, and there might have been a mechanical snail on one of the other books in the series. He thinks it takes place He describes it as having manga style art, but it could just have a strong style. He saw the book a few years ago. Many thanks again.

Possibly something from the Amulet series by Kazu Kibuishi?

We found it--it was the Amulet series. Thanks!
