Runaways - V. C. Andrews

'All for one and one for all' is the girls' motto. In the grim foster home for orphans run by Louise and Gordon Tooey, at least Brooke, Crystal, Raven and Butterfly have each other. Calling themselves 'sisters', together they can forget the past and dream of a new chance... a real home. Then they discover a secret even more haunting than Gordon's heavy boots pounding on the wooden floors. Their fragile hopes for a better life shattered, they escape the only way they can. Soon they are runaways in a borrowed car, desperately wishing to wake up one morning in a place of sunshine and love.
On the road the chains of sadness that bound them seem to melt away, and the kindness of strangers makes a secure future seem almost real. But the highway is a dangerous place, and soon they are penniless and more vulnerable than ever...
