I came to reading early. My mom used to dump me in the playpen with loads of picture books, and when I got tired of screaming, I
"read" the pictures until I went to sleep. 
As a child, I read voraciously. The "Alice" books by Carroll entranced me, also Grimm's Fairy Tales,
C.S. Lewis' Narnia books, the Oz books by L. Frank Baum, the Mary Poppins series, E. Nesbit (Five Children And It, The Phoenix and the Carpet), George MacDonald (The Light Princess, The Princess And The Goblin), Tanglewood Tales, etc. I liked escaping into a fantasy world that was much more exciting than my everyday life. I think this helped create an openness in me to subjects that most
would dismiss as "far out", such as nonphysical realities and spiritual concepts in general.
I got into poetry at a young age also. My favorite poets may be William B. Yeats and Tennyson, but I appreciate many others.
In adult literature, I appreciate writers like Kafka whose work integrates ideas and philosophy. Paul Auster's early work has this quality too (The New York Trilogy). I read little fiction these days, though I have a lot stacked up, waiting to be read. Metaphysics has kind of taken over my reading.
I believe Cosmic Consciousness by Richard Maurice Bucke was an important stimulus to my own experience of cosmic consciousness.
Seth was my introduction to channeling and I was fascinated by the concepts of time as an illusion, that we choose our parents, and of how everything we experience is a reflection of ourselves. I started with The Nature of Personal Reality, but it was Seth Speaks that really blew my socks off. That book took me to a whole different place. I felt like I was tripping while I was reading it, though I wasn't on anything except that book.
Ken Carey's Starseed Transmission books. They are like poetry.
All the Pleiadians books thru Marciniak, Bringers of the Dawn and Path of Empowerment especially.
Well, there's more, but I have to stop somewhere
