Review by Frank Plowright

Alina Tysoe begins My Sister the Werebeast by explaining how there was once a magical society, but it faded and was replaced by humans, so by the time we reach Whisper Cove in the present day almost all traces of magic have disappeared. Except, as seen on the sample art, perhaps some traces remain.

Mira and Rosie’s infant sister is the source. When Peanuts has nightmares things happen, and while there seems little actual magic left in the world there are plenty of ancient magical artefacts, and children are trained just in case magic re-emerges. In the case of Peanuts it’s definite, and while their parents are away adventuring Mira and Rosie have their work cut out as Peanuts is now transforming into a werebeast during the day.

Good natured comedy accompanies Tysoe’s bright, simple and attractive illustration from the start in what almost unfolds as a puzzle to be solved. Mira and Rosie can’t let anyone know about Peanut’s abilities, which are creatively exploited throughout, and as they research how to control her they also have to stop her manifesting magic because there’s a danger in others discovering she can. Peanut, though, is too young to understand what she can do and why it has to be hidden.

While everything connected with that plot is well handled, what runs alongside about Mira and Rosie taking part in school trials isn’t as convincing, and much of it comes across as inserted to use space. There’s a point to a rivalry with a brother and sister, but it might have been connected more smoothly. It’s also worth noting that when a malign presence joins the story it looks very similar to the strange creature from Spirited Away.

Young readers aren’t going to care about any of that, and should be captivated by Peanut and her sisters, and hope that Tysoe follows through with a sequel.
