With my publisher's permission I've put the first five chapters (53 pages) of Hal Spacejock online. There are 32 chapters in the book, so this represents just over ten percent of the total, which should be enough for anyone to decide whether it's their cup of tea or not.
You'll find the sample pages here. Right now they're page scans, but an electronic file is a possibility in the future.
Enjoy, and say hi to Clunk for me.
Simon Haynes is the author of the Hal Spacejock and Hal Junior series (Amazon / Smashwords / other formats)
