Voigt doesn't soft-pedal what it means to take care of kids when you're a child yourself; I remember the scenes on the road as both harrowing and specific. (There's a peanut butter sandwich-making scene that sticks in my head.) By the end of the first book, the Tillermans have found a place to live with their prickly grandmother, and in Dicey's Song there's a little more breathing room. Dicey is a wonderful heroine -- strong, independent, responsible even as she's totally overwhelmed by the amount of responsibility placed on her. She's also fairly androgynous -- short-haired, not into dresses, often mistaken for a boy. In later books, she begins a relationship with Jeff Greene (the protagonist of A Solitary Blue, and one of the main men on my friend Cyd's literary crush list, at least through high school).
This is one of the great things about Voigt's books: like L'Engle, she writes a number of books set in the same world but with a focus on different characters. The later Tillerman books can stand on their own, but if you've read Dicey's Song, scenes in A Solitary Blue and Come a Stranger take on greater resonance. Come a Stranger focuses on Dicey's friend Mina, an aspiring ballet dancer who faces racism at a New England ballet camp (she's black and from Maryland; perhaps one possible answer to Denise's question in the comments about diverse YA chick lit characters?).
The other Voigt book that's stayed with me is a totally different genre: Jackaroo: A Novel of the Kingdom. The current cover art appears to be unfortunately romance-novel-y; what I remember doesn't read that way at all. Jackaroo is set in a medieval-ish time and place called the Kingdom, and its heroine is a strong-willed, practical innkeeper's daughter named Gwyn. She discovers the mask and sword of the legendary Jackaroo (a Robin Hood figure), and decides to use the disguise herself to help people in need. It turns out that she's not the first person to have done this -- Jackaroo's identity is used by a number of people, for different reasons. It's a good mystery.
This thread is making me ridiculously happy.
