Reddit mentions of Assassin's Creed: Volume 3 Homecoming (A D.D. Warren and Flora Dane Novel)

Graphic novels:

• Assassin's Creed Subject Four - It combines the 2 graphic novels "The Fall" and "The Chain" in one and is basically the prequel to the present day story in the games. It's the oldest comic and quite hard to find a physical edition nowadays. If you can't find it, look for "The Fall" and "The Chain" seperately.
  
  
• Assassin's Creed Brahman - A comic from 2013 and quite hard to find physically, similarly to Subject 4.
  
  There are also newer comics published by Titan:
  
  
• Assassin's Creed - Has 14 issues, split in 3 volumes.
  
  Vol. 1 - "Trial By Fire"
  
  Vol. 2 - "Setting Sun"
  
  Vol. 3 - Homecoming
  
  
• Assassin's Creed: Templars - 9 issues, split in two volumes.
  
  Vol. 1 - "Black Cross"
  
  Vol. 2 - "Cross of War"
  
  
• Assassin's Creed: Last Descendants – Locus - A standalone miniseries, but it takes place between the first and second "Last Descendants" novel. It features some familiar characters from Syndicate, but it's only worth the read if you're reading the novels it's named after.
  
  
• Assassin's Creed Uprising - the final major arc from the comics. "Assassin's Creed" and "Templars" must be read first, read "Uprising" after that as it continues the stories and features characters from both previously mentioned series. It finishes a major present day storyline from the games, so it's definitely worth the read despite the issues of the format it's presented in. Has 12 issues, collected in 3 volumes.
  
  Vol. 1 - "Common Ground"
  
  Vol. 2 - "Inflection Point"
  
  Vol. 3 - "Finale"
  
  
• Assassin's Creed: Reflections - standalone mini-series, portraying a short adventure for each of the following assassins: Altair, Ezio, Connor and Edward. Should be read after "Assassin's Creed" and "Templars", but before "Uprising", but it doesn't really matter for the overall plot. It's more of a fun little adventures for each of these beloved characters and has an interesting reveal or two in there, but nothing major.
  
  
• Assassin's Creed Origins - another standalone mini-series. It's 4 issues follow the story of Aya after the events in the game Origins, so you should definitely finish it first before you read this one.
  
  And finally - Assassin's Creed Conspiracies. Originally a two-part comic in French, it has now been translated to English. Collected edition should be out on December 18th, 2018.

I think Google Play doesn't get all the issues and volumes immediately. Anyway, the third volume has recently been released, and it seems to be up on Amazon
