Her father is a handsome movie star who is amazingly rich and lives in a fabulous house next door to Cameron Diaz. He has a collection of incredibly cool vintage cars and buys Ruby all sorts of trendy and expensive clothes and gadgets. He enrolls Ruby into an exclusive school where the children of other movie stars go and where Ruby's elective is dream interpretation, of all the kooky "California" things. So even though you feel sad for Ruby for losing her mom, and she goes through tremendous grief trying to deal with it, you have the comic element of Ruby dealing with this impossibly fantastic life that most kids would love to live.
Told in the first-person, in engaging free verse, the reader sees what Ruby sees and learns what Ruby learns as soon as Ruby herself does. And the end is a surprise. So, get over the title and give it a read.
