Here's what Iris knows about her identical twin sister, Summer:

Everything that belongs to Summer is perfect, from her magnificent yacht to her gorgeous husband.

Summer's life will always be better than Iris'.

Nobody - absolutely nobody - can tell the twins apart. Even with $100 million at stake.

Against a backdrop of sparkling tropical islands, ocean storms, and outrageous wealth, The Girl in the Mirror explores the terrible consequences of greed, deadly lies, and out-of-control jealousy.
