Dear Donna Tartt,
Thank you for writing The Goldfinch. Although it took up a ton of my time, it was time well spent. Theo and Boris are characters I will remember forever. Their friendship, in the face of adversity, is flawed for sure. However, the loyalty they feel toward one another cannot be beat - not even by armed Russian gangsters. Popper the dog is used to symbolize the relationship between Theo, our main character, and his friends. Towards the end of the novel, Theo neglects Popper and he goes missing; nevertheless, he is found unharmed and ready for the next adventure.
I appreciate authors like you because much is left to the imagination of the reader. All too often, writers forget that we have minds of our own. Filling in the space between the lines is the best part about reading a book - thank you for not filling them in for me. After finishing your novel, unanswered questions stayed with me for days...just the way it should be. Good luck in writing your next piece - I hope it's not 800 pages long like the last one. Chop chop!
