Legion : the Many Lives of Stephen Leeds : An Omnibus Collection of Legion, Legion : Skin Deep and Legion

I have liked this one more than I anticipated. Narrating the life (and "adventures") of Stephen Leeds, a rich and very smart guy that is psychologically insane, but for a very interesting reason. He is very smart, so smart that he can assimilate knowledge very fast just by glancing at a book. But the way his brain works is, instead of "him" acquiring the knowledge, is an aspect of him who does. These aspects are hallucinations: fake people that his mind create (along with personality, past, likes, etc). This way he dominates a lot of different areas by having dozens of different aspects, which is complicated to handle for him and his mind of course.

With his aspects he became famous because he works like a private investigator, he takes some weird cases and can solve them on "his own". But the main story focuses over the character of Sandra; someone important that helped him focus his mind into these aspects but disappeared a while ago, to come back during the course of this book.

It's a short novel composed of three short stories, very easy to read, easy going and it displays some interesting questions from the point of view of someone who is determined as extravagant or insane, story evolves at a very reasonable pace until the end where it starts dropping things to the reader just before the story ends (with an open ending).
