Review: Awaiting the Doomsday by Paul Slutsky ★★★
Awaiting the Doomsday is an alien invasion story with an intriguing premise: a second sun suddenly appears in the sky. Astrophysicist Alan Norton makes the discovery that the object has a trajectory unlike any planet. Norton, along with other worldwide scientific leaders from Russia and Japan, among others, is tasked with contacting the craft to understand its motives.
