Anomaly — Scott Prussing

The world has changed -- and not for the better.
As the 21st century nears its midpoint, the world has become a far different place. Nearly three decades earlier, a time-travel experiment on the island of Alcatraz went terribly awry. Instead of opening a portal to the past, it opened an entrance to a parallel world. Through the portal came terrifying creatures who previously had existed only in humankind's legends and nightmares.
Along with the monsters came a mysterious plague -- for ten years no children are born anywhere on earth. Then, on the tenth anniversary of The Incident, a baby girl is born in San Diego. On each of the next six days, another child is born.
Each of the Seven develops a magical power; everyone except Leah, the first born. When Leah is seventeen, she receives an ominous message from the other world. The Seven must journey to Alcatraz and stop what is going to happen on a day which just happens to be Leah's eighteenth birthday. Otherwise, the world as they know it will cease to exist.
But Alcatraz lies five hundred very dangerous miles away, and there are no more cars, trains or planes to get them there. Even worse, the message doesn't tell Leah what is going to happen, or how they're supposed to stop it.
Filled with danger and bravery, magic and monsters, companionship and loss, Anomaly will keep you glued to its pages until the final, pulse-pounding sentence.
