An omega complex novel could refer to a novel that involves the concept of the omega in a complex way. In some fictional universes, 'omega' might be related to a certain type of character, like in werewolf or shifter stories where omega is a low - ranking individual in the social hierarchy. So, it could be a novel exploring the life, challenges, and growth of such an omega character.
I'm not sure of specific novels titled exactly 'omega complex novel'. However, in the werewolf genre, 'Bitten' by Kelley Armstrong has elements related to the omega concept. It shows different levels in the werewolf pack hierarchy and how the characters interact with the omega - like aspects of their society.

In my opinion, 'Death Note' has a highly complex plot. It's full of twists and turns, psychological battles, and moral conundrums. The story keeps you on the edge of your seat throughout.
