The year is 1759, London. Shakespeare's new estate is set on fire by Reverend Francis Gastrell, a man removed from history and his act of rebellion, covered by a sorry excuse.History repeats itself, almost 250 years later, when Luna Gastrell stands in turmoil due to her ever-simple and already-known ancestry taking a sinister turn.Luna realizes that there are many things she is ignorant of, including her connection with Lucier Hayden and Alastor Rhodus Morais, towards both of whom she feels an unexplainable affinity.A ploy of vengeance, illusions, betrayals, blooming romance and morally conflicting measures, and the cards lie in favour of none.

In the late 1970s, Vera Rubin showed that the flat rotation curves are ubiquitous in local spiral galaxies, and concluded that it is due the presence of invisible matter, the so-called `Dark Matter'. She remarked- ¿galaxies are surrounded by a dark matter halo that extends much further than their visible matter¿. These observational results were later supported by theoretical models of structure formation. Recent observations of high redshift galaxy rotation curves show remarkable differences in dark matter profiles compared to the local Universe. Therefore, there is an urgent need to repeat the `classical' observational study of Rubin et al. at high redshift with a large dataset.In this book, I have shown that dark matter is ubiquitous in star-forming disc-like galaxies at z~1, as well as extended the classical work to study the redshift evolution of dark matter halos. I have shown that dark matter halos have smaller and denser dark matter cores at z~1, which suggests that the predictions concerning the transformation of cusps into cores, which are observed in hydrodynamical simulations, indeed occur in nature.
