Free Download Rivers of London #5 Foxglove Summer by Ben Aaronovitch
When two young girls go missing in rural Hertfordshire PC Peter Grant is sent out of London to check that nothing supernatural is involved. It's purely routine, Nightingale thinks he'll be done in less than a day. But Peter's never been one to walk away from someone in trouble, so when nothing overtly magical turns up be volunteers his services to the local police who need all the help they can get. But because the universe likes a joke as much as the next sadistic megalomaniac, Peter soon comes to realise that dark secrets underlay the picturesque fields and villages of the countryside and there might just be work for Britain's most junior wizard after all. Soon he's in a vicious race against time in a world where the boundaries between reality and fairy have never been less clear!
