More consensus from me as well as a bit of disagreement! This is a fantastic book, and yes it has had hype but I don't believe for one minute that it's been undeserving.
Much of the book, as is, will be of most use to today's 'modern' mentalist rather than an old-school psychic such as myself. However Joshua's writing is excellent, giving you plenty of thoughts regarding the mechanics of each effect which leave you with plenty of food for thought on how to develop them into your own.
If you'll indulge me, I'll go through some of the effects:
Bendito
Metal bending has never been my thing so I can't rate this in comparison to other coin bending methods but out of curiousity I practiced it (didn't need much) and performed it to a few work colleagues and it hit home just as you'd expect it to.
Xijatsey
A nice little ploy to play in whatever card force takes your fancy, be it psychological or mechanical. Can be used as a reveal on its own or as an 'explanation' as to how you made your prediction.
CSICOP
A spec is shown a piece of card/business card etc. The audience are shown the exact same card. The spec names out loud what he/she saw on the card. The audience all saw something else. No switches, the audience sees the card
at the same time* as the spec.
One of the effects in the book that leave you marvelling at Joshua's thinking and ingenuity. This is definitely one for the stage and a LOT of rehearsal to get just right. I've been playing with this one in my rehearsal studio (aka living room) and have had it work and miss. Nothing wrong with the effect, it just needs a lot of practice.
*I emphasise that part heavily for a reason, most of us know of (a few) methods to produce essentially the same effect, but none that I know of where the spec and audience see the card
at the same time. I know, I did it again.
Fate Rules
A gem, an absolute gem. Love love love this effect. Can you tell I'm a bit fond of it? A True/False game using simple props from an old board game, Quizzled. (American readers might not know of this game, nor younger ones, but it's great fun, I used to play it as a kid all the time

)
A spec answers random questions with either a truth or a lie and you (or another spec) calls her/him out correctly every time.
There's SO many ways to utilise this effect. You can present yourself as a Truth Wizard, impart that ability to a spec etc. Once you get to the secret of the effect your mind just races with possibilies. Genius. Pure genius.
My Zeneration
The effect is as Tom described, 5 ESP cards each for performer and spec. The performer makes his selection
first and the spec next, each pair placed face down. They all match.
An excellent ESP routine which satisfies my psychic ability claims. Can even (and really SHOULD) be performed quite impromptu, I've done this one down the pub after a few..... shandies.
Deckquivoque and
Verbal Forking
Not just an effect (which ties in beautifully with
Xijatsey) but a treatise on using equivoque beautifully. I can't help but think Joshua should release this as a pamphlet in its own right as non-mental performers will get value from this.
Memorandum
I truly despise this effect, I really do. Why? Because it's so utterly brilliant and I'll never use it as it is so thoroughly 'modern'. One for the psychological mentalists, it's very Derren Brown and it's very very very clever! Joshua starts by stating that this effect is very hard to summarise, so what hope I've got I don't know, but I'll try.
Four specs: 1 is asked to think of a random, 2 digit number. No forces, it's a true free choice. The number is written down and countersigned by the 1st spec. The card is then shown to the subsequent specs and countersigned each time. A comical prediction is then displayed which leads to the specs all naming the number they countersigned, and they're all different! The performer shows the card with the correct, freely thought number, then goes onto explain WHY they saw a different number (Think of the 'Inluential' finale from Derren's Something Wicked). As an added (optional) kicker the performer displays a prediction of the original, freely thought number.
Invisible Brushes
A performance idea for those people who own Lior Manor's Invisible Touhes
Thwarpie
One of the deal clinchers that made me purchase Paralies. Not an effect but instructions on creating a brilliant utility device that is, IMHO, far better than some of the commercial and overly expensive ones out there.
Actual Proof
A wonderful effect that involves an entire audience becoming mind readers. An age old idea brought right up to date with some brilliant nuances from Joshua on how to maximise the impact to get a huge majority of the audience 'hitting'. It's a brilliant closer, especially I thought for a corporate gig, this would not look out of place at the end of Chuck Hickock's Mentalism Incorporated routine.
There are other effects which I simply haven't yet studied and really shouldn't review because of that, I don't believe in reviewing something I've just skimmed over.
And if all that wasn't enough ( and really, it is) the various sections are peppered with a few '
Pasteboard Interludes' where Joshua treats us (and they do feel like a treat) with some of his favourite card moves and tricks.
Overall
9.8/10

As I said, modern mentalists with the psychological thing going on will get more value from this than those who are partial to a reading or two or enjoy the dark side of life. Don't let that put those old-school performers off though, there's some genuinely brilliant thinking in here, Joshua has a very brilliant mind.
