More Than Human is widely lauded as the first literary science fiction book, and it won the first Hugo back in 1953. Seventy years later, it holds up.
While the premise sounds a little like X-Men—young outcasts with superhuman powers—this is in no way a superhero book. These are damaged people with inexplicable abilities who are trying to make their way in the world without revealing what they can do. The focus on character and the skill of the writing hasn’t aged at all, making this story an absolute classic.
Recommendation: Read it.
