A flash of blue - Maria Farrer

Guilt, grief and big mistakes... Amber is convinced that her brother's
death is her fault. It happened on the day that she'd taken
something of his, something precious, the very thing that gave him
his luck. Weighed down with grief, guilt and pressure to be the
perfect daughter, Amber turns to the one boy who can make her feel
better. But Tyler is in with the wrong crowd, and Amber finds
herself in big trouble: trouble that would never usually happen
to a girl like her. Only with her life having crashed around her
will Amber find a way to rebuild it, and to finally find out what
part she really paid in her brother's death.
