Fine, but not great. There's a lot of attention to historical detail, which I like, and the characterization is mostly decent, and it covers an interesting part of Christian history--the period between the crucifixion of Christ and the Pentecost, when the local and Roman leaders are trying to investigate and/or cover up the disappearance of Jesus' body from the tomb, and the believers know that Christ has risen but aren't yet sure what that means. The authors rather cleverly weave their original characters into the existing Bible story: Leah is the niece of Pilate and helps his wife deal with the dreams (mentioned in Matthew 27) that plague her over Jesus' death; Alban is the centurion whose servant Jesus heals (although, as another reviewer pointed out, Christ states in Luke that the centurion has greater faith than anyone in Israel, but Alban in the book doesn't really believe until the end).

But for all that, the book didn't wow me. The beginning was quite slow, and it all ends rather suddenly. And the developing affection between the two main characters feels rather forced and sudden at times; one chapter, Alban's an ambitious soldier marrying to elevate his social standing, and in the next chapter he's suddenly all tenderness and solicitude. So all told, the book was fine, but not great.
