The series

At a glance.

Emma Swan's illustrated detective series follows ten-year-old Silver, who lives aboard a cruise ship where her mum is Deputy Cruise Director. Each book is a self-contained whodunnit - vanished watches, a missing social-media influencer - solved by Silver as she snoops through restaurants, shops and swimming pools, usually landing herself in an ocean of trouble. Beneath the comedy runs a warm thread about making friends when everyone else is only on holiday, proving yourself trustworthy, and earning a little more independence. Katie Saunders's bright, characterful illustrations keep the pace zippy and the tone light. Fast-moving and genuinely funny, with satisfyingly twisty plots, it is an ideal step-up mystery for newly confident readers who want a heroine to root for.

    Silver's cases

    Two self-contained shipboard whodunnits solved by budding detective Silver.

    Every Cruise Ship Kid book is a self-contained mystery, so this collection covers the series to date. In the first, Silver cracks the case of a wealthy family's vanished watches while trying to prove she is best-friend material to newcomer Yana; in the second, aboard a glamorous new ship, she hunts a missing social-media influencer to show her mum she is responsible enough for a phone of her own. Both pair comedic shipboard chaos with a satisfyingly twisty plot and a warm heart about friendship, honesty and earning trust. Brightly illustrated and fast-moving, with the sensitivity low throughout, they make dependable, confidence-building reads for newly confident readers.
