The Williams Tapes (Rewritten)

A pair of siblings have recently graduated from middle school, landing them in their summer break. They have fun with their parents and with each other. However, their enjoyment doesn't last for much longer, when Victoria is then kidnapped for a reason that Darwin has to discover when undertaking a journey to retrieve his sister.

(Note: This is a rewrite of one I was working on that eventually hit the bucket because of how god-awful its writing was.)
