WEEK ONE

Above, by Leah Bobet (April 1, Arthur A. Levine)

Matthew has loved Ariel from the moment he found her in the tunnels, her bee’s wings falling away. They live in Safe, an underground refuge for those fleeing the city Above—like Whisper, who speaks to ghosts, and Jack Flash, who can shoot lightning from his fingers. But one terrifying night, an old enemy invades Safe with an army of shadows, and only Matthew, Ariel, and a few friends escape Above. As Matthew unravels the mystery of Safe’s history and the shadows’ attack, he realizes he must find a way to remake his home—not just for himself, but for Ariel. Young Adult.

After the Fall, Before the Fall, During the Fall, by Nancy Kress (April 1, Tachyon)

The year is 2035. After ecological disasters nearly destroyed the Earth, 26 survivors are trapped by an alien race in a sterile enclosure known as the Shell. Fifteen-year-old Pete is one of the Six—children born deformed or sterile and raised in the Shell. As the survivors grow sick and die, Pete and the Six struggle to put aside their anger at the alien Tesslies in order to find the means to rebuild the earth together. Their only hope lies within brief time-portals into the recent past, where they bring back children to replenish their gene pool. Meanwhile, in 2013, a brilliant mathematician works with the FBI to solve a series of inexplicable kidnappings. Suddenly her predictive algorithms begin to reveal more than just criminal activity.

The Road of Danger (Lt. Leary/RCN, Book 9), by David Drake (April 3, Baen)

Captain Daniel Leary with his friend and spy, Officer Adele Mundy, are sent to a quiet sector to carry out an easy task: helping the local admiral put down a coup before it takes place. But then the jealous admiral gets rid of them by sending them off on a wild goose chase to a sector where commerce is king and business is carried out by extortion and gunfights. With anarchy and rebellion in the air, a rogue intelligence officer plots the war that will destroy civilization and enlists the help of a brute whom even torturers couldn’t stomach. And, of course, it’s up to Leary and Mundy to put a stop to the madness.

Alien Diplomacy (Katherine “Kitty” Katt, Book 5), by Gini Koch (April 3, Daw)

Being newlyweds and new parents is challenging enough. But Jeff and Kitty Martini are also giving up their roles as super-being exterminators and commanders in Centaurion Division while mastering the political landscape as the new heads of Centaurion’s Diplomatic Corps. Enter a shadowy assassination plot and a new set of anti-alien conspirators, and nothing will ever be the same.

Triggers, by Robert J. Sawyer (April 3, Ace)

On the eve of a secret military operation, an assassin’s bullet strikes President Seth Jerrison. He is rushed to the hospital, where surgeons struggle to save his life. At the same hospital, researcher Ranjip Singh is experimenting with a device that can erase traumatic memories. Then a terrorist bomb detonates. In the operating room, the president suffers cardiac arrest. He has a near-death experience—but the memories that flash through Jerrison’s mind are not “his” memories. It quickly becomes clear that the electromagnetic pulse generated by the bomb amplified and scrambled Dr. Singh’s equipment, allowing a random group of people to access one another’s minds. And now one of those people has access to the president’s memories—including classified information regarding the upcoming military mission, which, if revealed, could cost countless lives. But the task of determining who has switched memories with whom is a daunting one—particularly when some of the people involved have reason to lie.

WEEK TWO

Immobility, by Brian Evenson (April 10, Tor)

Before the Kollaps, Detective Josef Horkai was the one they called in whenever an investigation hit a wall. He’s still pretty certain he’s the best, even if there are very few other people still alive to compete with, even if the rules of the game have changed. Only problem is, he’s been exposed to something that’s slowly killing him. His hair has fallen out, his teeth are all but gone, his legs are already all but useless, and he can feel the feeling slowly seeping out of his fingers. Which is why they’ve kept him frozen, held in suspended animation until they figure out what’s wrong with him. Only he can feel time oozing slowly past, has a vague sense of the world going on without him. And then suddenly, someone claiming to be a friend thaws him out, tells him he’s needed. Something crucial has been stolen—though with the pain in his head it’s hard for him to keep straight what and why. He’s got to get it back or something bad—what was it again?—is going to happen. And he’s got to get it back so they can freeze him again before his own time runs out.

Accompanied by the beautiful assassin called Violin, Joe follows a series of clues to find the Book of Shadows, which contains a horrifying truth that threatens to shatter his entire worldview.
