A very nice review here of The Shadow of the Scorpion by John Markley. Obviously this is of the Night Shade version since the Macmillan one isn’t out yet. Here’s a sample:

I really liked this book. It provides plenty of the intense action Asher is known for, and continues to explore the setting of Asher’s future history. On a purely action/adventure level, the book definitely delivers, with Asher’s usual talent for excitement, description, and visceral power brought to the forefront. It also gave me what were probably the two things I most wanted from Asher: more information about the character Ian Cormac, and a closer look at the society of the Polity itself.
