There are soo many series I absolutely loved.
Harry potter- all time favourite!!

Before Harry Potter, I used to devour Hardy Books. Joe Hardy was my fav♥️😁

Another series I return to when I dont have anything to read is The Hidden Legacy by Illona Andrews. Sure, the covers are the cheesy and the worst but I like kick-ass heroines. It’s kinda guilty pleasure😝😄

I dunno whether you can call it a complete series since the final book is yet to come out (I will most probably die of the anticipation) but the Kingkiller Chronicles is another of my faves. The first line of the prologue of Name of the Wind got me hooked. ♥️
