How am I celebrating ACOTAR birthdays??
By giving you guys TOG birthdays XDDDDD... Oh and their zodiacs... Oh and there's Feyre too, though she's not in TOG (I'm so lame, sorryyy).
Feyre: 21 December (Sagittarius)
(Exactly a day and a month after Rhys's, lol)
Aelin: 3 May (Taurus)
Rowan: 16 July (Cancer)
FYI, all these are trustworthy, they're the characters' official birth dates, I checked and double checked and checked online too. :))
