my sister read a Colleen Hoover book in which the narrator is too embarassed to keep a diary, so she writes 'letters' to her favorite talk show host Ellen DeGeneres. The entire book is formatted as letters written to Ellen.... what the actual fuck is going on

does any1 else have trouble with reading ebooks? Every once in a while there will be a book that is impossible to find in print and so I have to get an EPUB and put it on my nook, it's just so much harder to read and I can't tell why
