How far would you go to stand out?
From the author of "Nerve".
What if the ultimate makeover had a deadly consequence? Aislyn has always been cripplingly shy - hiding from the world white wishing she could step into the spotlight. So when she's offered Charisma, an underground drug guaranteed to make her shine, she can't resist the temptation. The effects are instant: Aislyn's charming, funny and popular, just like she's always wanted.
But suddenly so are lots of other people... Then the doctor behind the "miracle" drug disappears and people's behaviour starts spiralling out of control. What if the symptoms are contagious... or worse, deadly?
One dose is all it takes: Take it or Leave it.
