Ender's Game by Orson Scott Card

In order to develop a secure defense against a hostile alien race's next attack, government agencies breed child geniuses and train them as soldiers. A brilliant young boy, Andrew "Ender" Wiggin lives with his kind but distant parents, his sadistic brother Peter, and the person he loves more than anyone else, his sister Valentine. Peter and Valentine were candidates for the soldier-training program but didn't make the cut - young Ender is the Wiggin drafted to the orbiting Battle School for rigorous military training.

Ender's skills make him a leader in school and respected in the Battle Room, where children play at mock battles in zero gravity. Yet growing up in an artificial community of young soldiers Ender suffers greatly from isolation, rivalry from his peers, pressure from the adult teachers, and an unsettling fear of the alien invaders. His psychological battles include loneliness, fear that he is becoming like the cruel brother he remembers, and fanning the flames of devotion to his beloved sister.

Is Ender the general Earth needs? But Ender is not the only result of the genetic experiment. The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. Ender's two older siblings are every bit as unusual as he is, but in very different ways. Between the three of them lie the abilities to remake the world. If, that is, the world survives.

Cascade by Lisa T. Bergren

Gabi knows she's left her heart in the fourteenth century and she persuades Lia to help her to return, even though they know doing so will risk their very lives. When they arrive, weeks have passed and all of Siena longs to celebrate the heroines who turned the tide in the battle against Florence - while the Florentines will go to great length to see them dead.

But Marcello patiently awaits, and Gabi must decide if she's willing to leave her family behind for good in order to give her heart to him forever.
