Aunt Lynn at Jessewave Reviews has given A Portrait of Emily a good, insightful review:
Here's a part of it...
I trust Bowie to give us a solidly-written, complex murder mystery, and this story delivered. Even with everything going on, it didn’t feel like it was over-packed with plot: the continued effects of Emily’s molestation on her and those around her; the reveal of Anthony’s childhood; the reappearance of Jeff’s ex, Joey; the murder of both Joey and Emily’s father; and the child prostitution ring. While we know who kills Joey (we are there when it happens), the reveal on the murder of Charles Hastings was unexpected for me, and in the end, it all wrapped up neatly.
