Slaves Of Sleep Books in Order

The Slaves Of Sleep books follow Jan Palmer, a wealthy but unhappy young man whose life changes when an ancient copper jar is opened in his home. The jar holds a powerful jinni, and the curse that follows pulls Jan into a second world that humans usually reach only in sleep.

The idea is simple and fun: sleep is not just rest. It is a doorway.

In Slaves of Sleep, Jan’s waking life is already a trap. He has money, a large house, and a family business, but he is pushed around by relatives, staff, and obligations he never wanted. Then a prowler, a sealed jar, and an angry jinni turn his private misery into a much larger problem. On Earth, he is caught in the aftermath of a crime. In the other realm, he becomes tied to a swashbuckling life of danger, magic, and war.

That other world gives the series its color. It draws on Arabian Nights-style fantasy: jinn, ifrits, hidden powers, dangerous bargains, strange courts, and battles between those who control sleep and those enslaved by it. Jan is not a polished hero when the story begins, which is part of the point. The fantasy adventure forces him to act, choose, fight, and grow into a braver version of himself.

The Masters of Sleep continues the premise after the first book’s discoveries. Jan is again caught between ordinary reality and a hidden magical order, with sleep, identity, and power all tangled together. The sequel keeps the same taste for swordplay, old curses, and sudden reversals, but it also broadens the conflict around who controls the border between the human world and the world beyond sleep.

The two books are best read in order. Slaves of Sleep explains Jan Palmer, the jar, the curse, and the rules of the dreamlike realm. The Masters of Sleep works better once you know why Jan matters and what he has already survived.

The tone is fast, pulpy fantasy rather than modern slow-burn worldbuilding. Expect cliffhangers, villains with old grudges, magical threats, and a hero learning that escape from one life may drop him into something far more dangerous. For readers exploring Hubbard beyond science fiction, this short series is one of his clearest fantasy starting points.
