Liars' Room

"Simon is a liar. Stella and Alex know this about their new stepbrother, so they aren't bothered by his stories about their new house. But Simon is getting harder and harder to ignore, as his cries for attention become increasingly dangerous and difficult to explain. Stella and Alex have to consider...could Simon actually be telling the truth? Will the three siblings be able to put aside their differences to save their family...before it's too late?"--
