The Adjacent

In the near future, Tibor Tarent, a freelance photographer, is recalled from Anatolia to Britain when his wife, an aid worker, is killed--annihilated by a terrifying weapon that reduces its target to a triangular patch of scorched earth. A century earlier, Tommy Trent, a stage magician, is sent to the Western Front on a secret mission to render British reconnaissance aircraft invisible to the enemy. Present day: a theoretical physicist develops a new method of diverting matter, a discovery with devastating consequences that will resonate through time.
