Pre-order Matt Parker's new book "Love Triangle: the life changing magic of trigonometry"!

As a bonus for anyone who pre-orders direct from me on Maths Gear, I have commissioned three (special, limited) × edition book covers as a collaboration between me and print-artist Paul Catherall. They're pretty special. You'll get one free while stocks last.

All books will be signed by me. All book covers will be signed and numbered by me. The first 1,001 orders will get a free "simplex edition" cover, the next 2,024 covers will be "tetrahedron edition" and the remaining 5,995 covers are the "triangle edition". They will be assigned to orders in that order, so earlier pre-orders get the more-limited cover. Once the covers run out, people will have to be satisfied with just a signed first edition of the book.

Love Triangle will be published in the UK on Thursday 20 June 2024. By entering your payment details you'll have a copy reserved in the queue but you'll not be charged until we actually post you the book in the week of publication. And we'll send you an email right before then to confirm your details and give you a chance to change anything or cancel before the payment goes through.

Thanks so much for your support pre-ordering the book! It really does make a difference as publishers use pre-orders as a metric to determine how much to promote a book and how many copies to print and ship even to other retailers.

Also, if you cannot afford to pre-order the hardback copy from me, that is completely fine. You can absolutely get a not-signed copy cheaper somewhere else. It's on Amazon and if you pre-order on Waterstones with the discount code 1+2+3+4+5+6=21 you'll get 21% off.

The USA edition will be out on August 20 and Penguin USA will be offering pre-order bonuses as well. You can see USA pre-order options here: https://www.penguinrandomhouse.com/books/672455/love-triangle-by-matt-parker/

And there is an option no one should order. I realised that there are 168 prime numbers below 1,001 so I'm going to allow a maximum of 168 orders of a box-set with three books in the three book covers, all with the same matching prime number. But it's going to be real expensive. Don't order it. Unless you really want matching numbers and you want to support the Stand-up Maths youtube channel by paying too much to buy the same book three times, in a box.

Thanks again!

Matt


NOTE FOR NON-UK COUNTRIES: This will be the hardback UK edition of Love Triangle and the postage is to ship it from England to you (not tracked or signed for).

NOTE FOR USA: Yes, postage to the USA is real expensive. Sorry. The pre-order price is the worst-case. If we can find a cheaper, (slower) way to get your copy to you, we'll offer the chance to switch at the time. Or you can change your mind and cancel your order.

NOTE FOR GERMANY: Currently German customs are rejecting the majority of items shipped from the UK so we cannot guarantee your order will not be cancelled. We're hoping to find a way to get them into Germany but we'll cancel your order if we cannot.

NOTE FOR AUSTRALIA: This is what you get for living so far away. And I'm not putting all your copies in my suitcase for the next time I'm over visiting family.
