I give it 3.5 stars out of 5. Hats off to author Katsu for giving us mostly unpredictable and — more importantly — plausible plot twists. Reminded me of Michael Crichton at his finest.

Some minor quibbles:
- Theresa slapping Eric (seemed out of character for her because she was cool, calm, and collected).
- When Lyndsey was at Theresa's house for dinner, Lyndsey asked permission to look around while her host cooked dinner. I dunno, it seemed Theresa would have said no and she would have showed her guest around after dinner. Might have been more plausible if Lyndsey went to the bathroom and snooped around without Theresa's permission.
- Theresa constantly thinking that she's doing everything for her son. Duh.
- More showing rather than telling. For example, near end, Theresa goes over to Lyndsey's apartment with the same bottle of alcohol that Lyndsey already has and points it out with inner monologue.
And the ending of Red Widow rang a little hollow, but I enjoyed the book overall and will read future novels by her.
