This is Why We Lied: Is Karin Slaughter's Will Trent 12 Worth It?

Book twelve in a series is a risky place to jump in, and a risky place to be a publisher, because by now your readers have strong opinions. They know what Will Trent does when he walks into a room. They know the bruises, literal and otherwise, that Slaughter likes to pile onto her characters. So the question with This is Why We Lied isn't whether it's a competent thriller. The question is whether it still has something new to say this deep into the run.

My short answer is that it's a safe bet at £5.99, provided you already like the Will Trent books. That's a price you'd barely notice, roughly the cost of a coffee and a pastry in most UK train stations, and for a full-length crime novel from a No.1 Sunday Times bestselling author it's hard to argue with.

Now, I should be clear about how I work. I haven't sat down and read this cover to cover for the purposes of this review. What I have done is dig through the product listing, the series background and a good deal of reader commentary on how the Will Trent books tend to land. There's no Amazon rating on the listing I was working from, so I can't wave a star score at you. Instead, I'll tell you what the series reputation suggests and where I think you should be cautious.

Why Starting at Book 12 Is Your First Decision

Let's deal with the elephant in the room. This is the twelfth Will Trent novel, and the listing is upfront about that. Slaughter's series has a habit of rewarding people who've followed the characters over time. Relationships shift, old cases cast long shadows, and a good chunk of the emotional payoff depends on knowing who these people were three or four books ago.

Can you read it cold? Probably, yes. Crime series of this vintage tend to be written with newcomers in mind, at least enough that the central mystery stands up by itself. But you'd be getting the plot without the full weight of the characters, which is a bit like turning up to a wedding halfway through the speeches. You'll follow it. You won't feel it quite the same way.

The Slaughter Formula, and Whether It Still Works

Karin Slaughter has built her name on dark, procedural-heavy suspense, and the series sits firmly in that tradition. Expect a crime at the centre, a pile of secrets that people would very much prefer stayed buried, and a title that does a lot of thematic work. This is Why We Lied is a title that tells you most of the cast are hiding something, and I'd wager the fun is in working out who and why.

The danger with a long-running series is repetition. Twelve books in, an author can start leaning on the same beats. Reader chatter around long-running thrillers like this one tends to split into two camps: people who love the familiarity and people who've started to feel the seams. I can't tell you which camp you'll fall into, but I'd suggest that if the last Will Trent you read left you cold, this one is unlikely to reconvert you.

What £5.99 Gets You

The price is the most persuasive thing about this listing. At £5.99 you're paying less than a pub pint in plenty of UK cities, for something that'll occupy you for a few evenings or a long train journey. Paperback thrillers of this calibre can easily creep towards double that, so the pricing feels fair, even slightly generous.

Worth mentioning, though, that the listing doesn't specify the format in the information I had, so check whether you're buying the paperback, the ebook or an audio edition before you click. Format affects both the experience and whether £5.99 is a bargain or merely reasonable.

The Honest Downsides

First, the obvious one. Slaughter writes grim. If you want a cosy, low-stakes mystery to wind down with, this isn't it, and the series reputation for darker content is something to weigh up beforehand. It's a thriller that wants you slightly uncomfortable.

Second, the series-depth issue I mentioned earlier. Starting here means you'll miss context, and the book can't fully compensate for that. Third, the lack of a visible Amazon rating on the listing I worked from means I can't point to a crowd verdict. Take my read as informed by the series pedigree rather than backed by a score.

Who Should Actually Pick It Up

If you've read the earlier Will Trent books and enjoyed them, buy this without much hesitation. It's cheap, it's from a reliable name, and it's the next chapter in a story you're already invested in.

If you're new to Slaughter, I'd go back to the start of the series, or at least pick up an earlier entry first. You'll get more from this one when you arrive with the history. And if you simply want a punchy, twisty crime read for a holiday or a commute, it'll do that job too, with the caveat that you'll miss some of the character texture.

It's a solid, sensibly priced entry from an author who knows exactly what her audience wants. Not a revelation, but at £5.99 it doesn't need to be.

✓ Pros

  • At £5.99 it's very affordable for a full-length thriller from a major bestselling author.
  • Fits neatly into an established series, so existing fans get the continuity they want.
  • The title and premise promise a mystery built on secrets and deception, which suits Slaughter's strengths.
  • A reliable pick for fans of dark, procedural-style crime fiction.

✗ Cons

  • As book twelve, newcomers will miss a lot of character history and emotional context.
  • The darker, grittier tone won't suit anyone after a lighter, cosy read.
  • There's no Amazon rating available on the listing, so there's no crowd score to lean on.

Our Verdict

If you're already a Will Trent reader, this is an easy, affordable buy at £5.99 and I'd grab it. If you're new to Karin Slaughter, start earlier in the series so the characters land properly, and steer clear altogether if you prefer your mysteries gentle.
