During summer break, eight-year-old Joshua sits around the house playing superhero videogames all day. His twin sister, Annika, spends her free time performing super deeds for people in need. When the two siblings team up, Joshua learns that being a superhero involves much more than leaping from buildings or defeating larger-than-life villains. Superhero Siblings marks the first book in a delightful new series about two siblings ready to take on the world.
