Getting Started With The Mortal Instruments
Cassandra Clare City Of Bones is the first book in a seven-book series that follows Clary Fray through the Hidden World of Shadowhunters. It came out in 2007 and has sold over 30 million copies worldwide. The book is straightforward urban fantasy with a lot of lore to absorb. Here is what you need to know before you dive in. The book is available from Penguin Random House, Barnes & Noble, Amazon, Book Depository, and most major retailers. The paperback runs about $11.99. The ebook version is around $8.99. If you are looking for the signed first edition or special collections, expect to pay significantly more on the secondary market. I have seen copies listed for $200 to $400 depending on condition and whether they include promotional material. Just don't bother unless you are collecting seriously. Start with City Of Bones. Do not start with The Lost Library of the Unicorn or any of the companion books. The series is linear and each book references events from the previous one. Skipping ahead will leave you confused about character motivations and plot threads. The seven main books are City Of Bones, City Of Ashes, City Of Glass, City Of Fallen Angels, City Of Lost Souls, City Of Heavenly Fire, and The Last Hour.
I made the mistake of reading The Mortal Prince short story before finishing the main series. It spoiled a major emotional beat in City Of Fallen Angels because the short story takes place after those events. Do not read any side material until you finish the core seven books. Wait until after. Then go back and read everything else, including The Chroniclers series, Tales from the Shadowhunter Academy, and The Wicked Powers trilogy.
Understanding The World Without Getting Lost
The book introduces a lot of terminology quickly. Downworlders, Nephilim, warlocks, faeries, vampires — it is a lot to track. The best approach is to read without stopping to look up every term. Take notes on the ones that appear repeatedly. After finishing the book, go back and fill in the gaps using the glossary that Clare provides in the back of most editions. Here is something most new readers miss: the rune system in City Of Bones is not random decoration. Clare built the runes around a logical framework where each symbol modifies Clary's innate ability to see hidden things. When she gets the angel rune on her wrist, it is not just a cool visual — it changes how she interacts with the entire Shadowhunter world. Understanding that connection matters more than memorizing every single rune name.

Common Problems People Have With This Book
The pacing in the first half of City Of Bones drags. Clare spends about 120 pages establishing the mundane world before anything supernatural happens. Some readers drop it there. I have seen forums where people claim the book gets good only after page 150. That is mostly accurate but worth pushing through because the setup pays off. The mundane sections establish Clary's relationship with her mother, which becomes critically important later. Another issue: the romance between Clary and Jace moves fast for some readers and feels rushed for others. The book is written from Clary's first-person perspective, and she is sixteen. Her emotional responses are meant to feel immediate and intense. If that bothers you, reread the later books where both characters have more agency and the relationship develops more gradually.
A Specific Problem And Workaround
When I first read City Of Bones, I got stuck trying to map out the geography of the Hidden World. The book mentions the Shadowhunter Institute, the Pandemonium Club, the Morn, and various downworlder territories but never gives a coherent map. I wasted about two hours drawing my own version. Then I found the official maps published by the author, which clarify the layout much better. Use those instead of making your own. They are available on Cassandra Clare's website and in most editions of the book. There is also the matter of the seraph blades and how Shadowhunter magic works. The book explains the basics but leaves gaps that frustrate detail-oriented readers. My workaround was reading The Rise of the Institute by C.V. Wade after finishing the book. It fills in a lot of the historical and magical context that Clare assumes you already know. It is not required reading but it helps significantly with the lore questions that come up.
What The Book Does Not Do Well
Be honest about the limitations. The female side characters in City Of Bones are underdeveloped compared to the male cast. Jocelyn, Valentine's wife, appears in the beginning and then largely disappears. The faerie court members get less depth than their male counterparts. If you are reading for strong female character development beyond Clary, this book will disappoint. The later books improve on this considerably, but City Of Bones specifically has that gap. The villain Valentine is also somewhat one-dimensional in this first volume. He functions more as a force of plot than a fully realized antagonist. That is a common issue in first-installation books and Clare addresses it in subsequent volumes by showing his motivations more clearly. Do not judge the entire series by how Valentine is handled here. If you want a similar book but with tighter prose and better female character development, try The Golem and the Jinni by Helene Wecker or City of Stars by K. Ancrum. Neither is in the same universe but they share the urban fantasy genre and handle characterization more evenly.

That is the practical rundown. Read the book in order, use the official maps, skip the companion stories until after you finish the main series, and push through the first hundred pages. The world gets interesting once it starts moving.
