Oh, it's free if you already have Thorns - I will update the game file on Sunday and it will be found under the Extras menu.
It's just a small collection of scenes (totals about 20,000 words) from the POV of the TROS love interests that was promised as part of the Kickstarter.
As I recall, each character has a minimum of two, with some backers kindly pledging so they could request certain extra scenes (that everyone then gets to enjoy). Those characters with extra TROS scenes are Sofia, Frederique, and Guillaume.
The TTOW ones will be released once the rest of the game routes are complete. ^_^
