Best of all Worlds is an outstanding YA dystopian speculative novel written by prize-winning Canadian author Kenneth Oppel. This novel combines themes of climate emergency, pandemic, survival, politics, racism and teen passion in the claustrophobic melting pot of a strictly enclosed environment. The prologue announces a death the opening page and then plunges the teenage narrator Xavier Oak into an alien landscape from where the novel builds tension throughout its 240 pages to an explosive conclusion. This is a novel which requires the reader to continually question their understanding of events, both fictional and in the real world. It is a work of the highest quality, which I (considerably older than the target audience of 14/15+) immensely enjoyed reading.
Xavier has reluctantly accompanied his dad (Caleb) and heavily pregnant step-mum (Nia) for a decompressing break at their lakeside holiday cottage, whilst his older teenage brother and mum have remained in the city. Missing his family, gaming fan Xavier just wants to listen to the music that his brother Sam has downloaded to his phone whilst working on the latest escape strategy for the Dungeons & Dragons game he and his city mates are engaged in. He is not impressed on the first morning to find that the Wi-Fi is down, thinking that this is part of Nia‘s plan for a tech-free getaway. Imagine his shock when he realises that the familiar lakeside scenery has been replaced by farmland, crops, chickens and goats and that all three inhabitants of the cottage have a strange triangular pattern of puncture wounds along their spines! After detailed exploration it becomes apparent that the family are trapped inside a dome from which their attempts to escape are fruitless. What’s more they appear to be overseen by an invisible benevolent force with the power to intervene when necessary; this becomes apparent following the traumatic birth of baby Noah.
… Fast forward three years, Xavier desperately misses his mum and Sam and constantly worries about what has befallen them. However, he has adapted to the self-sufficient lifestyle and the family have assumed that they have been kidnapped by aliens, and have given up attempts to escape. They are settled farming their crops, preserving food for the winters and tending their animals. Then without warning a new family are dropped into the dome. A family from the opposite side of the political divide, a family who own guns and a crossbow, a family who believe in deep-government conspiracy theories. The father, Riley Jackson, is convinced that the dome is some kind of deep state experiment, thinks that the Oaks have taken a cowardly and submissive approach to their captivity and is determined that he will lead his family out of the dome and back to their home in the deep south of America.
Tensions build at multiple levels as the families become acquainted. Firstly there is updated news about the climate emergency and pandemic status on Erf (as Noah refers to the planet he has never seen) and the measures being taken to prevent climate refugees from entering North America. Then there is the sexual tension between teens Xavier and Mackenzie (who is pining for the boyfriend she has left behind). Finally, the shifting levels of trust and distrust between the adults who represent different ends of the political spectrum bring a sense of foreboding and menace to the previously peaceful dome.
This is such a clever book which can be enjoyed purely as a compelling dystopian thriller, or can act as a prompt to conversation about the many issues contained within the narrative. I think that it is likely to spark many interpretations, ideas and questions. I saw the dome as a metaphor for the barriers being constructed between different sections of society and the tendency to interact mainly with others within one’s own particular thought bubble rather than engaging in dialogue to understand the views of others. Without any doubt I can state that this will be one of my choices for top books published and read during 2025.
I highly recommend this to secondary school librarians and readers aged 14/15+ who want a thought-provoking, enthralling read.
