"Now in his late-sixties, Daniel lives in quiet anonymity in a converted guest cottage in the Hollywood Hills. A legendary artist, he's known for one seminal work-Thorn Tree-a hulking, welded, scrap metal sculpture that he built in the Mojave desert in the 1970s. The work emerged from tragedy, but building it kept Daniel alive and catapulted him to brief, reluctant fame in the art world. Daniel is neighbors with Celia, a charismatic but fragile actress. She too experienced youthful fame, hers in a popular television series, but saw her life nearly collapse after a series of bad decisions. Now, a new movie with a notorious director might reignite her career. A single mother, Celia leaves her young son Dean for weeks at a time with her father, Jack, who stays at her house while she's on location. Jack and Daniel strike up a tentative friendship as Dean takes to visiting Daniel's cottage--but something about Jack seems off. Discomfiting, strangely intimate, with flashes of anger balanced by an almost philosophical bent, Jack is not the harmless grandparent he pretends to be."--,Provided by publisher.
