Ivan hurried away from the ridge. His heart beat fast and his hands were shaking. The shock of seeing Cal appear was considerable. Yes, he and Reenie had persuaded Hugo to play his drums at sunset, but Ivan realized now that the last thing he expected was to succeed. Ivan, Cassie and Wilfred, Reenie and Cal desperately miss each other; the friendships they made in their similar but different parallel worlds six months ago. When Cal reappears in Ivan and Reenie's world, the turmoil and restlessness that has lurked in each of them explodes into real life, throwing all, and the unsuspecting Jess, into a whirlwind of adventure, uncertainty and discovery. Switch is the sequel to Rowena Evans' novel, Drums and Power Lines.
