Sat down last night and read this entire book, tears welling up throughout. Not sure if it's the book or my mental state, however, so take that with a dripping of salt, warning or recommendation. 
 June and Greta are sisters, a couple of years apart in age and different in many ways. June, the main protagonist, the younger, feels ordinary. The most special thing about her, in her mind, is her Uncle Finn. Finn's her godfather, an artist living in NYC in the '80's, dying from AIDS. Before he dies, however, he paints a portrait of the sisters, forcing them together, holding them together forever, he hopes. 
 Most of the story takes place after his death. June meets Finn's "special friend" and tries to hold onto her beloved Finn through Toby, who is also in mourning and also dying. 
 There's so much going on in the story, so many underpinnings that Brunt deals with so well. Because it's June's storytelling a lot goes missed by her, but the writing conveys a depth that a fourteen year old, even one like June, might lack. 
 Well crafted story. Subtle and touching. Heartrending, even.
