This book made it onto the Giller Prize shortlist. I have a bit of a problem with that. Not because it's not a good book but because the author, although born in Canada, has not spent very much time living here. She was raised in New Zealand which is where this book is set. There is not a smidgeon of Canadiana in it. It's hard enough to make a living as an author in Canada; these prizes are a godsend for struggling writers. The final outcome saw the Giller Prize going to another ex-pat, Sarah Bernstein, but at least she grew up in Canada. Okay, rant over.

I'm sure we all remember studying Shakespeare's Macbeth and most of us probably identified the title of this book from that play. In Macbeth the title character is told that he will only be defeated when Birnam Wood comes to Dunsinane. Since trees can't move Macbeth figures he is safe. But, indeed, Birnam Wood does come to Dunsinane because the advancing soldiers cut off branches to hide their approach to the castle and it looks like Birnam Wood is moving. So, what does that have to do with a book about eco-gardeners in New Zealand in 2017? The group's founder, Mira, came up with the name to identify the group with a concept of plants taking over where they haven't been found before. The group plants seeds and seedlings in disused public places and then sells or otherwise distributes the produce. Mira has the grand view for the group that it will become so established it will make enough money to support her and all the other gardeners. Meanwhile, her roommate and second in command, Shelley, is responsible for most of the grunt work and she's tired of that. She wants to leave but doesn't quite know how to tell Mira. Then in walks Tony, an original member of the group who has been away for a number of years. He had and still has a thing for Mira. Shelley figures if she can just get him to go to bed with her, Mira will be so upset she will kick Shelley out. There's just one flaw, Tony isn't interested in Shelley.Meanwhile, Mira is on track to take the group up to the next level. She hears of an abandoned farmstead near a landslide owned by the Darvishes. She goes there to check it out and finds that the property is about to be sold to an American billionaire. Robert Lemoine ostensibly wants to buy property to build a shelter in the event of a global holocaust. In fact, this is a cover story for his mining of an adjacent park for rare minerals he needs for his drone business. It's not quite clear why Lemoine wants Birnam Wood to be on the property but he offers to bankroll them as a pilot project. Tony is against doing business with Lemoine but the rest of Birnam Wood go along with it. Tony decides to investigate (he's a free-lance journalist) and runs across the illegal mining operation. Down at the farm things go pretty well until Lemoine hands out LSD and then a fatal accident occurs. Lemoine is very smart and figures he can cover up what happened. He also figures he can eliminate the threat that Tony poses. What do you think will happen? Let me tell you, it's nothing good but I was surprised by how bad it actually turned out.

In addition to my dislike of this book being nominated for the Giller Prize, I also found a lot of the explanations of the leftist politics of the Birnam Wood crew juxtaposed with the aggressive capitalism of Lemoine to be just too much verbiage. Really, how often do we have to listen to the polemics of either side to get the concept that they are polar opposites. On the plus side, if you read this book like a modern-day thriller you'll probably enjoy it. ( )

Wow. Richly portrays its characters thoughts and motivations, and seems to capture the feeling of the time in a way I haven't encountered elsewhere. What an ending. ( )

A group of young people run a startup that plants gardens in unused public spaces and distributes the produce to the food-insecure in New Zealand. The leader of the group is investigating planting a garden on a large stretch of private land near a public park, when she meets a billionaire who is considering buying the land. He offers to invest in the startup, which creates controversy among the startup members who are torn between taking his money and standing up for their principles. Things get complicated because the billionaire wants to use them as a distraction from illegal mining he is doing on the adjacent public lands.

This takes a long time to turn into a thriller... the first half is more of a soap opera about the relationships between the various characters. None of the characters is likeable, or even very sympathetic. The book gets more engaging once the action picks up in the second half, but then the ending is very sudden and felt like a cop-out. ( )

Strong character development, good original story and I don’t want to give up the plot. Young climate activists interact with a billionaire aka Elon Musk. Secrecy, illegal mining and a natural park. Highly recommended for both characters and unexpected plot. ( )

There wasn't much I liked about this book. I certainly wouldn't call it a thriller, until the last 1/10 of this too-long story. At times it read like junior high school girls' spats about boys. True, there was something shady going on, but nothing made me care very much about the mystery. The ending was horrible. If I hadn't been on a long vacation trip, I don't think I would have finished.
