Elliot and Fiona Post are the natural children of the Prince of Darkness Lucifer and the immortal goddess. They themselves do not yet know about this, but the infernals, or fallen angels, as people call them, know it very well. In a mortal battle for the souls of the twins, two powerful forces collide - the servants of light and the warriors of darkness - and the balance of the world depends on which side Eliot and Fiona take. The beginning of a new epic by Eric Niland in its imagery, the brightness of the characters' characters and the unpredictability of situations, in that the young heroes end up in is quite comparable to the famous “Chronicles of Amber” by Roger Zelazny. This is the opinion of readers and critics who greeted the first book of the series with delight. The novel is being published in Russian for the first time!
