無論如何，秘密都有浮出水面的一天……
　　Cassie Romano出生的那天，她父母原先所居住的城市在市長按下按鈕後，便有大約五千座泳池的水量將其淹沒，成為一座人工湖。十二年後，Cassie覺得這個湖有蹊蹺，底部似乎埋藏著什麼不可告人的事情。所有的相關報導都在粉飾太平，一味地強調新城的美好，全面封殺湖底舊城的過去。她的同學Liam也有同感，便每天陪她一起前往湖中的禁區。
　　隨著暑氣越來越盛，湖裡的水平面也越降越低，剛好方便他們兩個一窺湖底如幽靈般的舊城，以及找尋當初急欲被掩蓋的秘密。然而，就像游泳的人往往一不留神就游離岸邊太遠，Cassie也驚覺自己似乎已經沒有轉身放棄的餘地，只能和Liam硬著頭皮向謎團前進。她有沒有機會及時揭發湖底的真相？或者，她有沒有足夠的勇氣承擔足以撼動整座城市的後果？（文／博客來編譯）
