How is #36 not on there? That book is easily the worst thing in the entire series. It's nonsensical, pointless, does nothing to develop the characters, introduces plot points that are never mentioned again, not to mention just mindblowingly stupid. And the way they escape is never appropriately explained - how did Marco and Rachel get from their (incredibly injured) battle morphs to ORCA (which requires air) without drowning? Not to mention that Marco states he can't hold the hatch closed, and then Jake's plan is to have him hold the hatch closed until the appropriate moment. NO. NO. BAD AUTHOR. BE CONSISTENT WITH YOURSELF. GOD.
I mean, I hate #41 more. I hate #41 with the furnace-like hate that you could use to fuel a freight train from New York to Las Vegas. I have dreams where I rip #41 apart with my bare teeth and then feast on the papery remains. But at least #41 has a few good lines in it. #36 has exactly one fun line ("Mr. Psycho's Nautical Toybox and Graveyard"), and it's in the preview chapter at the end of #35, so there is no reason for #36 to exist as an entire book at all. Well, that and the Luminar's kinda cool.
I voted for #41 by the way, even though #36 deserves it more, just because I can't resist an opportunity to make jabs at the trash-heap that is The Familiar.
