@Lynnixo Well for me it's ten or more than that. I really enjoy reading it and the plot became more interesting in each book respectively. I've read the TOG series too (yes i agree it wasn't the greatest) and is into Sarah more now thanks to the ACOTAR series. In my opinion, ACOTAR series is better than the TOG. You might find something common in both of the series though ;)
I haven't but it is on my TBR list. So on the scale of one to ten how great is the book and how high on the list should I priotise it? haha although I have read Sarah's throne of glass series though but it wasn't the greatest tbh
