Stone and Sky [Aaronovitch, Ben]

The tenth novel of the bestselling Rivers of London urban fantasy series returns to the adventures of Peter Grant, detective and apprentice wizard, as he solves magical crimes -- this time, while on a family vacation in Scotland

Peter Grant is north of the border—but don’t worry, he isn’t in Scotland alone. It’s the summer holidays, so everybody has traveled up with him: Dr. Walid, Thomas Nightingale and his latest apprentice, Abigail Kamara; Peter’s best beloved Beverley Brook, the twins, Peter’s mum Rose, and, since his dad can’t be left on his own, he and his trumpet are coming too. And given Aberdeen has its own small but vibrant jazz scene, it would be criminal if there weren’t some gigs whilst they’re in town, so the band is also driving up.

What could go wrong—right? Stupid question really.

Why are there magic gulls terrorising the seafront? And what does this have to do with certain ancient families that seem to have a mystical connection with the sea and the massive offshore industry that has made Aberdeen the oil capital of Northern Europe?

When a man with gills is found dead on a boulevard, Police Scotland reluctantly avail themselves of Peter’s expertise. Between keeping his dad, the band and a pair of hyperactive twins out of trouble, Peter has to discover who the victim was, who killed him and why.

To solve this one Peter Grant and Beverley Brook are going to have to risk getting out of their depth—literally.
