Poorly researched, only sticks to diary format part of the time, humour is crass and cruel with a character who is meant to be an unreliable narrator but who reliable tells you what she's lying about all the time.

This was a fun read. A good mixture of disturbing scenes and comedic passages, definitely in the same vein as How To Kill Your Family. 

"I just want some stability in my life. I want a house with four front windows and two hanging baskets and a garden where I can grow things. A bigger lawn for Tink. And a better job. And a book deal. It’s not too much to ask, is it?"

Rhiannon, 27, lives with her cheating boyfriend Craig and Chihuahua Tink. She hates her job and has anger management issues stemming from deep-seated childhood trauma. In her free time, she plays with Sylvanian families, walks her little dog and kills people like the unhinged  psychopath and serial killer she is.

I have a penchant for female serial killers who go after bad men but she is actually trying to lure them in by walking around deserted alleys at night. She doesn't shy away from killing women, and she derives sexual pleasure from her bloodthirsty deeds. So I was quite uncomfortable reading her matter-of-fact diary entries about balancing her deadly shenanigans with meeting friends and pretending to be normal.

I have to say her daily kill lists - strangers who annoyed her that day by queue jumping, overcharging or other heinous crimes - are kind of relatable but after a while she makes very sweeping statements and I found myself on them twice ("Everyone who lives or works in London" and later "the entire human race").

Once she complains about people who make grammatical mistakes but says "me and Craig" instead of "Craig and I" all the time! Personally, that needled me greatly, but Rhiannon's thoughts and behaviour are at no point logical, as she admits herself. For example, absolutely everyone who manages to lock two in-flagrante rapists in a van would drive that van to the nearest police station. But not her. Oh no. She finds a much more deranged but ever so entertaining solution.

I actually felt sorry for her a few times about how utterly unhappy she seems to be. But instead of throwing her boyfriend out (she knows all about the affair) or changing her job she gets her kicks by killing people. At the end, the tally I counted was 11 people, two of them historic. That's a lot! You need a strong stomach for this book - the gory stuff often comes out of nowhere. She also swears like a whole ship full of sailors.

Despite all this I was kind of mesmerised and read this twisted, deeply gripping and darkly funny tale as fast as I could. It's brilliantly written but dare I say 100 pages too long, especially as this is only the first of five books in this series.  The cliffhanger makes me want to read the next one NOW because I must know how she gets out of the situation she is in - pregnant and just about to hack her dead lover to pieces when the doorbell goes!

"How many men does it take to tile a bathroom? One – but only if you slice him veeeeery thinly."

This serial killer premise is unoriginal, there's too much explanation for why she is the way she is, and the narrative voice is deeply unpleasant.  The excessively short chapters, journal entry style, daily minutae, boyfriend drama, and catty tone make this feel like an evil Bridget Jones.

This book just keeps doing the same things over and over, and her narrative voice doesn't change, so it's just really tiring to read this un-pc, fat phobic, agist, condescending, judgemental POV for 450 pages.

She tells so many unnecessary lies, and it's frustratingly ludicrous that she wouldn't get called on them.  Especially when she's lying to a journalist - why make up a lie that you could easily disprove with a google search?  The book letting the character get away with this undermines the believability of the book overall.

I wanted to like this - it's occasionally funny, and she's mostly hunting rapists and pedophiles so there's a justified revenge element. Ultimately, although it was a quick, easy read, there was nothing memorable here, and it wasn't as funny as it was grating and unrealistic.
