Getting Your Head Around the Fourth Book in the Peter Grant Series
The Peter Grant novels by Ben Aaronovitch are urban fantasy detective fiction set in modern London with a heavy dose of magic and police procedure. Book number four, "Rites of Passage," continues following Officer Peter Grant as he navigates supernatural cases within the Metropolitan Police. If you are trying to figure out where to get it or how it fits into the broader series, here is a practical rundown. "Rites of Passage" came out in 2015. It features Peter dealing with an ancient evil connected to the Tower of London and a mysterious figure named Dora Skirth, who shows up more prominently in later books as well. The plot involves a curse, some serious magical escalation, and the kind of procedural police work Aaronovitch is known for, except the suspects sometimes have fangs or can turn into mist. The book is available through several channels. Amazon sells both the Kindle edition and the paperback. Audible has the audiobook narrated by the always-solid Simon Vance, who does the entire series and actually sounds like he knows what he is doing, which is more than I can say for a lot of audiobook narrators I have sat through. Libraries carry it too, obviously. If you are after a physical copy, your local bookstore or Waterstones will usually order it if they do not have it in stock.
One thing people tend to miss when jumping into this series is that you should actually read them in order. This is not one of those fantasy series where you can plonk yourself down at any point. "Rites of Passage" builds on events and character development from the first three books, particularly the relationship between Peter and his mentor Jean-Baptiste, and the way the magical side of the Metropolitan Police operates changes subtly from book to book. Reading out of order will leave you confused about why certain characters matter or why particular magical rules exist. I ran into a specific issue once when recommending this to someone who had only read the first book. They started at "Rites of Passage" and were completely lost on the tone shift. Aaronovitch gets darker and more emotionally complicated as the series goes on. By book four, Peter has been through things that make his usual sarcastic internal monologue feel almost desperate rather than just quippy. The reading experience changes significantly depending on where you are in the sequence, so starting mid-series basically ruins the emotional arc. Another thing worth noting is the pacing. Aaronovitch writes like someone who enjoys a puzzle box, and "Rites of Passage" is no exception. The magical mystery unfolds methodically, with red herrings and investigative detail that can make it feel slow if you are expecting non-stop action. The payoff is solid, but you have to commit to the procedural rhythm. It is not a flaw, just something to be aware of before you invest your time.
If you want the complete series order, it goes like this: "Broken Homes," "River of Blood," "Whispers Under Ground," "Rites of Passage," "The Hollow Man," "False Souls," "The Hanging String," and "Aftermath." Each one is roughly 350 to 450 pages in paperback, so budget accordingly for the full read-through. The audiobooks are slightly longer per volume due to narration pace, but Vance keeps you engaged enough that you barely notice. For pricing, the Kindle edition typically runs around seven to nine pounds depending on sales and your region. The paperback is usually between nine and twelve pounds. Audiobook subscriptions through Audible or similar services often include these titles in their catalog, so if you already pay for one of those, you may not need to buy anything separately. Library copies are free if you have a card, though you might be on a waiting list depending on your branch. A few caveats. The magic system in these books is dense and occasionally inconsistent when Aaronovitch prioritizes plot over explanation. Some readers find the romantic subplots underdeveloped or forced, especially as the series progresses. And while the London setting is vivid and well-researched, the actual police procedures take liberal license with reality, so do not use this as a guide for how the Met operates. It is entertainment, not a training manual.

If none of the Peter Grant books are your thing, there are other urban fantasy options that handle similar ground. The Dresden Files by Jim Butcher is the most obvious parallel, though it is more American and faster-paced. Charles Stross's Laundry Files takes a much drier, more bureaucratic approach to magic and government, which some people prefer. Both are solid alternatives if you want the same general vibe with a different flavor. The main takeaway is that "Rites of Passage" is a competent entry in a well-constructed series, and it works best if you approach it in sequence. Get it from whichever retailer is most convenient for your budget and format preference, and do not skip ahead. The story rewards patience, and the world Aaronovitch built is detailed enough that going in blind will only frustrate you.
