Unfortunately author Barbara Haworth-Attard had to cancel her 2011 Fox Cities Book Festival appearances due to illness, but her book Theories of Relativity is still well worth the read. Sixteen-year-old Dylan has been kicked out by his mother. Life on the streets is brutal, but Dylan is determined not to make the same poor choices he sees the other street kids make. Every day Dylan’s options seem to shrink, but he observes closely and formulates his own theories about how to survive. Sometimes, Dylan doubts whether he can really make it on his own in a world of drugs, violence, and exploitation, but does he really have to?
