Currently reading the sixth book in the Ender series. The story picks up just after Ender and his sister, Valentine, left earth for a new space colony – never to return. The plot centres around the kidnap of Ender’s ‘jeesh’ (aka clique) still on Earth, which accelerated led to the rise to power of Peter Wiggin, Ender’s equally brilliant but frequently ruthless elder brother.

About a quarter of way through now.
