The This by Adam Roberts (Gollancz, £16.99)
Imagine a social media app implanted in the roof of the mouth for more immersive connectivity. This one small step turns out to be a giant leap in human evolution, a sort of telepathy that brings everyone together as parts of one vast, gestalt consciousness. But is that really such a great idea? Roberts takes a classic trope of speculative fiction, combines it with current preoccupations and views the whole in the context of religious belief and Hegelian philosophy. The result is dazzlingly inventive, exciting, funny and addictively readable.
