A tree is a beautiful and wayward thing. It grows in twists and contortions, curling towards light and water. Place a seed and you cannot predict which way it will grow, if at all.
So, what do you do? You cut it into a precise 2x8 format and line them up next to each other. If one has an imperfection, you toss it away as waste.
The yew tree's revenge is coming. And it may well take the form of cutting humans up into a precise 2x8 format. Then it will go back to growing into beautiful, wayward shapes.
