Just about to finish the first book of ShadeSlinger. Really liking it so far. Definitely going to immediately go into book 2.
I like that the main character doesn't immediately become overpowered and doesn't do everything right. Also, the author is absolutely a WoW player.
None of what you mentioned purposely hunt humans. Shark 'attacks' very rarely end with a complete devour. It's the investigative bite that is usually deadly. Squids don't activately hunt humans either. In fact, they largely leave humans alone. Cougars are territorial but don't actively hunt...
There are 6 that are considered 'human hunters'. As in, deliberately target humans. Just not defensive or opportunistic attacks. Technically 7 if you separate Nile crocs from saltwater.
Tigers
Lions
Polar Bear
Leopards
Nile and Saltwater crocodiles
Reticulated Pythons
This series had me hating it and loving it. I'm glad the stat dumps slowed down drastically further in you got. Book 14 was a great book though and he ended it...fucker. I went to listen to book 15 and, well, not released yet.
