House of Earth and Blood has no bonus chapters; House of Sky and Breath has three and House of Flame and Shadow five, spread across retailer editions. Each sits at the chapter fans read it. Important: House of Flame and Shadow is set largely in Prythian and leans on A Court of Silver Flames, so read all five ACOTAR books before House of Sky and Breath. Two of the anchors (House of Sky and Breath ch. 22 and 57) come from a single fan source.
