For those of you outside of Singapore, the book is now available for ordering!
The paperback can be ordered from the main book page. The shipping zones are set by Singapore Post, although it's a good bet that many of you who may want to order are in Zone 3; if you're not sure, just read the description for each PayPal button on the page. I'm happy to sign and personalize your copies. Prices are in Singapore dollars (SGD), with the book at $25.00 SGD plus variable shipping (Z1 = $5.00 SGD, Z2 = $7.50 SGD, Z3 = $10.00 SGD); currency will automatically be converted by PayPal upon transaction. Please allow 2-3 weeks for delivery.
The e-book edition can be purchased and downloaded from Smashwords for only $3.99 USD. I've just been informed that it has been accepted into the Premium Catalogue, which means it'll be available at the Apple iBookstore, Barnes & Noble NOOK bookstore, Kindle ebook store, and several others in a couple of weeks; I'll update here once this is the case.
In the meantime, you can buy the DRM-free multi-format e-book directly from Smashwords. You only need buy it once and you can download it as a PDF, ePub (for Apple iPad/iBooks, Nook, Sony Reader, Kobo, and most e-reading apps including Stanza, Aldiko, Adobe Digital Editions, others), mobi (for Kindle devices & apps), Palm Doc, RTF, and Plain Text. Then, all you have to do is upload it to your preferred e-reader(s). Since there's no DRM, you're free to move the e-book between devices. Easy!
I'm going to be getting the word out on the book soon, so if you're interested in reviewing a copy for a print publication or high-profile blog, please let me know.
Update: The paperback has now been confirmed as stocked at Books Kinokuniya on Orchard Road, and the e-book is now available at the Apple iBookstore, the Barnes & Noble NOOK Book Store, and the Diesel eBook Store.
