A book has been released called A History of Notable Shadowhunters and Denizens of Downworld: Told in the Language of Flowers by Cassandra “Cartwright” Clare and Cassandra “Starkweather” Jean. It is inspired by the Victorian Language of Flowers.
It basically has many pictures of different flowers and explains what kind of flower they are, plus extra information about those flowers. What the Cassandras are doing are they’re making a book where instead of flowers, it is different characters from The Mortal Instruments, The Infernal Devices, The Dark Artifices, Tales From the Shadowhunter Academy, and The Last Hours. Cassandra Jean will be drawing portraits of the characters, and Cassandra Clare will be revealing exclusive details and notes on the characters! Pre-order here!
