Everything to remember before the next A Court of Thorns and Roses book

You remember the wings.

You remember the mating bonds.

You probably remember Nesta and Cassian's training sessions better than the political situation on the continent (or maybe that’s just me).

But with Sarah J.

Maas 's next A Court of Thorns and Roses book approaching, some details suddenly feel more pressing.

Who is Koschei again? Where did we leave Elain and Lucien? And why are people talking about a sword from an entirely different series? The last ACOTAR installment, A Court of Silver Flames , gave Nesta a love story, a new community, and a very expensive bargain with the Cauldron.

Since then, Maas has expanded this world through her Crescent City books, leaving ACOTAR readers with developments they might have missed.

Here’s what to remember before opening A Court of Splintered Harmony .

Warning: Major spoilers for the published ACOTAR books follow.
