Hiding Cracked [EPUB ebook] 

A blackmail letter arrives at an inopportune moment, and the recipient’s name is blurred out. Who is the ruthless missive meant for?
In the powerful sequel to Watching Glass Shatter, Olivia is the first to read the nasty threat. When the mysterious letter falls into the wrong hands, her sons try to figure out who’s seeking revenge on them.
Across the span of eight hours, members of the Glass family contemplate whether to confess their hidden secrets, or find a way to bury them forever. Some didn’t learn an important lesson last time, and as each hour ticks by, the family has to come to terms with what happened in the previous months.
Their lives are about to shatter into pieces once again, and this time the stakes are even higher.
