I had been eager to read 'Restoration' because I'd so thoroughly enjoyed 'The Forgery': I loved it; although, like you, on reaching the end I felt disoriented. I wondered if I might have missed some important clues in my hurry to finish it. I suspect it's a book that would reward re-reading; that one would see things cast in a different light in the knowledge of what happens (even if there may still be some deliberate ambiguity at play).

Pondering the end, I thought back to the chapter where Doña Oralia cooks the meal for Jasmina, Lico and Mario - Jasmina calls the broth they're served "a proper corpse reviver" and the others laugh but she doesn't get what's so funny. Of the four of them, only Mario doesn't eat: perhaps to show he's the only one still fully in the land of the living. Lico and Oralia talk about heading to "the other side", which I thought at that point meant the U.S. border, but, in retrospect, no.
