I'm a big fan of the Monkeewrench series by PJ Tracy and Monkeewrench #6 - Two Evils (or Off the Grid for US readers) is the latest installment. We find Grace relaxed for the first time in a long time, wearing a dress and enjoying the high seas with ex-FBI agent John Smith. However their peaceful existence is shattered when two men board their boat late on night and try to kill John. We later find out that John has been monitoring the internet for terrorist groups and accidentally stumbled upon a Halloween terror plot.A big part of the Monkeewrench series is the suspense in each book, and whilst Two Evils has some great moments of suspense, there isn't that same build up of tension that you find particularly in the first few books. That being said, the book was well written and the moments of suspense that were present had me on the edge of my seat. The plot was very good, with enough complexity to keep me guessing, though the final 'encounter' was a bit anti-climatic with very little action. I especially liked the sub-plot between Grace and Magozzi, and am looking forward to it being explored more in the next novel. Overall a good solid, enjoyable read which will appeal to both fans of the series and new readers.[A review copy was provided by Penguin Books]
