"My name's Jules. From the window of my Paris apartment, I'm looking in horror at the piles of bodies in the street below. My parents are on the other side of the world. They're almost certainly dead. My older brother, Pierre, can only drown his sorrow in drugs, but I must look after Alicia, a little girl who somehow escaped the virus and is all alone. But what can I do for her? My only hope is to join the other Warriors of Time masters... This meeting is where I'll find out who Khronos really is..."You choose which volume to read first.
