In order to survive, one must embrace change. Some changes arise from conscious decisions - but most remain cloaked in the shadow of the unknown. Aiden and Cheyenne Kinsey understand this far too well. As two young adults living in Los Angeles, their city of angels and big dreams have long since transformed into the tar pit of a dysfunctional family and tattered chances. With no guiding light to illuminate their way, they choose to take matters into their own hands by creating their own toxic hope - and they'll use any means necessary. Through artificial highs and grievous lows, their bond as siblings has almost frayed into nothing. Can the abruptness of hardship hope to amend their ruined tether - or will it instead destroy what remains of them? Two thousand miles east, twins Paul and Ruth Reagan live in a seemingly perfect world. They have been reassured with the promise of a steady future and immersed in the lushness of the countryside for all of their lives. But even this beautiful paradise has shadows ravaging its landscape. Inner turmoil taints the Reagan household, bundling itself tightly enough to eventually combust. When one devastating blow sets undeniable change into motion, can their idyllic home endure the oncoming tide? The Unknown will blacken the horizon far too soon. Four lives will attempt to cling to the remnants of an entangled past they would all rather forget. Yet it is in the discord of inescapable change that the most fragile of threads could become the strongest of them all.
