How do you get someone who loves the English language to give a book five stars? Write it in dictionary entry format, which is exactly what David Levithan has done. 
 The Lover's Dictionary charts the course of a relationship, but instead of flowing chronologically, the book is alphabetized by the nouns, adjectives, and verbs that the main character uses to describe their relationship. It's part poetic love story, part mystery, as you use the entries to figure out exactly what happened between the two people, exactly what went wrong, and whether they salvaged the relationship or decided to end it. The outcome is a wonderful and captivating story that is almost hypnotic as you read it. 
 The dictionary-format style of the novel isn't the only thing unique about The Lover's Dictionary. The two characters in the relationship remain nameless, with the main character addressing their partner as "you" throughout the entire novel. With David Levithan's reputation for writing LGBTQIA characters, I was quite intrigued by this, as it's up to the reader to interpret the relationship as they like. (view spoiler)[Later on in the book it is heavily implied eventually that the couple is heterosexual, with "you" becoming pregnant (even though this doesn't suggest a gender identity), and "I" referring to themselves as the boyfriend, which was altogether a little disappointing. (hide spoiler)] 
 Besides the format itself, I loved the story for the Levithan's writing style itself. The entries are brief, quick views into the couple's life, ranging from only one sentence to at most two pages (although usually ending up at about half a page long). The main character is very eloquent yet not overly wordy, and the reader is led to believe that this could even be their diary entries. It's very personal and private, as the main character isn't writing to explain things to the reader, but to communicate with their partner. It ends up feeling like the literary equivalent of shifting through someone else's old photographs, trying to piece together the story behind them.
