Alex Verus is in trouble - again. Or perhaps that should be Alex Verus is still in trouble, because this is a continuation of the trouble he was in last time, under a death warrant from the Mage Council. He's only managed to sidestep it because his old boss and longtime enemy Richard Drakh has once again got him in his power and this time Anne is involved as well. Alex feelings for Anne are... complicated (even more so because he won't acknowledge them).
Apart from the fact that Richard has threatened to kill all of his friends if he doesn't return to work for him, Alex is somewhat surprised when his old enemy turns out to be almost reasonable, seconding him to the Dark Mage Morden, who is the only Dark Mage on the Light Council. Morden - after being a deadly enemy in several previous books - also turns out to be a decent boss, and Alex is drawn closer to the political centre of magic in Britain. But he still has a foot in both camps and the light mages are convinced that Richard and Morden are planning something big, so Alex is conscripted to report back. Finally, with some bargaining power, Alex gets the Council's death sentence lifted. It's interesting to note that the Light Council has actually done more to hurt Alex and his friends than the Dark mages have, and they remain unpredictable and vindictive, while the Dark Mages have some obscure objective that Alex can only guess at.
This story is spread over a longer period that previous Alex Verus books, but the pacing is still smart and the twists many and various. At last Alex is starting to be proactive and (prompted by Arachne) starting to plan long-term. There's a twist in the ending that makes me eager to see what happens is Alex Verus #9.
