The Perks of Being a Wallflower question

Back in 2022, my best friend bought me a copy of perks of being a wallflower for my birthday from barnes and noble. It was an edition with the same cover as the 20th anniversary edition, however, it was closer to being square compared to the standard 5 by 7 edition that is being sold in stores. Long story short, I lost it and am hoping to find another copy just like it because it had a lot of sentimental value! I have been looking everywhere online to find one just like it. If anyone knows specifically what printing edition I am talking about or knows where I can find one, please let me know :')
