Students are dying, and this time, it's not Spearwood's fault. Someone is picking off those close to Avalon, and she fears she may know who it is. But can she accuse the boy she once gave her heart to? With the school on lockdown, moving around becomes even more difficult, limiting where students can be. Avalon feels isolated and cut off from everyone she could turn to. When the final trial for the year arrives, she finds herself paired with an unlikely team, but they may be exactly who Avalon needs in order to survive her second year at Spearwood.
