Var and her friends gather at a fantasy book festival abroad to see their idol – Bjorn Kraksson, the mysterious author behind the Disa book series. But Bjorn lets them down and then disappears  without a trace. After this, the teenagers can barely believe their eyes, as it seems like the entire setting of the book series, with its monsters and endless marvels, begins to spill over into reality.

Dream Disa is Eggertsson’s third book about the girl who was once a regular teenager in Reykjavik, vanished after an adventurous battle in a far-off land, but lives on through the writings  of Bjorn, her friend from the past. Gunnar displayed uncommon imagination in his previous books, Dead Disa and Devil Disa, and he doesn’t compromise in this the final book in the series.
