Michael J. Sullivan is a favorite author of mine and when I heard about a new book offer through Kickstarter I jumped aboard and it was well worth it.
Hollow World was a great read. Loved the concept, loved the story, loved the writing. I only wished it had gone a little deeper so I could feel the characters a little more. It felt almost rushed.
Overall, good book. If another book is ever written about Hollow World, it will definitely be on my to-read list.
