A review over at Tor.com:
Broken Homes is the fourth instalment in Ben Aaronovitch’s bestselling Peter Grant series, after last year’s Whispers Under Ground. If you’re new to the joy that’s PC Peter Grant and the mysteries he investigates under the supervision of DCI Thomas Nightingale—England’s last officially practising wizard—Broken Homes is not the best place to start. Unlike Moon Over Soho or Whispers Under Ground, it doesn’t give you much time to get your feet under you before it starts setting up its dominos and knocking them down.
The knocking down is, in places, rather literal.
