B&N preorder sale April 17 to 19

Barnes & Noble is holding a pre-order sale for members of Rewards (10% off) and Premium & Rewards (25% off) from April 17 to 19.
You can get a bargain when you pre-order Usurpation, the third book in the Semiosis trilogy, which will be published in October this year.
If you’re not a B&N member, you can pre-order the novel, too. Links to your favorite bookseller are here.
Usurpation starts where the second novel in the series, Interference, ended with an epilogue: A Pax Institute has been established on Earth, three rainbow bamboo grow there, the first of their species on humanity’s convulsed home planet. Stevland sends them a message telling them they must dominate the Earth and its humans. Levanter, one of the bamboos, asks Stevland how to carry out this impossible task. The answer will come in one hundred ten years. It might be too late.
Carnivory is not the worst thing a plant can do.

Preordering a book can make a big difference to its success. Pre-order sales are used by retailers to decide which books to stock and promote, and pre-orders allow publishers to anticipate how many copies need to be printed and how the book should be distributed. Pre-orders are also used by online booksellers to make algorithmic recommendations.
After you read a book, leave a review somewhere online! That’s another big difference you can make to its success.
