If you find the topic of non-human intelligence, esp. octopus intelligence interesting, you may find Adrian Tchaikovsky's children of Ruin series worth your time. The 2nd book, without ruining too much of the story, has octopii as one of the central characters. [1]
Going out further afield, exploring forms of intelligence & cognition that are very different from humans, Peter Watt's blindsight (firefall) series is an idea-filled, dense, very satisfying read. [2]
