Time, they say, is an illusion. Mercy discovers the truth of this when she meets the Tancred Nine, but she would describe it more as delusional.
To love a time-traveller comes with many surprises and a good deal of danger. The passages of dark matter are not empty, and there are those who guard them jealously. First Mercy discovers the threat of the past, then she discovers the greater threat of the future. Yet the greatest danger of all can be the unknown, and the fear of the unknown, which comes in many disguises.
The Tancred Nine is an adventurer with many wild ideas, many elaborate plots, and many strange beliefs, but most of all this is a man of humour and excitement. Mercy finds that her once timid and tedious life is turned upside down when she falls in love with the most delusional creature of all.
