Emma and Dave perfectly captured the various nuances of bullying, the emotions and consequences of being a victim, and even the avenues toward a solution. Pick up "Bluetooth & The World Wide Web" today and laugh, cry, and learn more about the concept of bullying, and how it can be defeated!"Malcolm Clarke, Durham Ct. Cllr, UK:"The authors cover a lot of ground in this look at computers and technology issues set in an insect world. E. Rachael Hardcastle's proven ability to take wide-ranging, serious issues and re-package them in a thought-provoking way is evident throughout as you learn about networks, communication, fake news, cyber-bullying, hacking and even racism in a story spun around the original masters of a web; the spider. The co-authors subtly satirise the many pointless divisions and prejudices we encounter in the digital and non-digital world every day and aside from the deeper themes, the plot is rich and the metaphors are vibrant and clever."
