Snekguy's 'Pinwheel' series has covered a wide range of situations with extraterrestrials being prominently featured. All his plots have been good and well thought out. The writing has a good style and is technically accurate. Correct spelling and good grammar make a book much more enjoyable (as an editor - not for this author - I spend a lot of time making sure other people's work is as well presented as possible), well developed plots are the icing on the cake.
This is, arguably, the best piece that Snekguy has written so far and it is well worth any reader's attention.
My only criticism would be that the sex scenes are a little too long and detailed. Many readers will, no doubt, disagree.
No, I'm not going to tell you what it is all about. Why spoil it for everyone. Read it and you will see. You won't be wasting your time.
