Nabeel Qureshi is an extremely bright man and has a wonderful story about how his search for God was fulfilled, published in the book Seeking Allah finding Jesus. This is the first book I recommend to anyone interested in Islam. His story tells how he changed from following Allah & seeing Isa as a prophet of Islam to seeing Jesus as the living Word of God. He also does a wonderful job of presenting a genuine, human face of the Muslims he knows and loves.
It is a very human story that is very positive about all people and the reader doesn't even realise they are learning a lot of Islamic and Christian theology at the same time. This is why it is my top book recommendation. This video is a great introduction to Nabeel and his story. Here is his website.
