Wind from the Wilderness - Rowntree Suzannah - Bog

Hunted by demons. Lost in time.
Welcome to the First Crusade.
Syria, 636: Heretic invaders circle Jerusalem. Young Lukas Bessarion is determined to defend his homeland, but with the Byzantine armies in retreat, it's up to the Watchers to produce a miracle.
Instead, disaster strikes. The Watchers are slaughtered. And Lukas is hurled across the centuries to a future where his worst nightmares have come true...
Constantinople, 1097: Seven armies march east to liberate Jerusalem. Desperate to find his way home, Lukas joins them - alongside Ayla, a heretic girl on her own quest for vengeance.
If Lukas succeeds, he'll undo the invasion and change the course of history.
But only if he survives the war.
Only if his enemies from the past don't catch him.
And only as long as Ayla never finds out who he really is.
If you love books full of dark magic, bloody warfare, and star-crossed love, then you'll be spellbound by this sweeping historical fantasy!
