There is *nothing* better than paperback special editions (+review of Ninth House and Throne of Glass)

I essentially only read paperbacks (excepting audiobooks and my kindle... basically, I just don't like hard covers whoops). I found many of these second-hand on ebay, as well as new on bookshop.org and amazon. Where do you search for your coolest books?

Books mentioned: 

Ninth House by Leigh Bardugo (paperback edition from India)

The Secret History by Donna Tartt (Popular Penguins edition)

A Discovery Of Witches/The All Souls Trilogy by Deborah Harkness (UK edition/ Headline edition)

Throne of Glass paperback boxset by Sarah J Maas

Anthony Horowitz set including Magpie Murders, The Word is Murder, and The Sentence is Death
