▸ A summer by the sea

Wren is spending the summer with Nana June on Gull Island, where the lighthouse has been dark since Grandpa Ellis's last season. The old stories say Old Moonfin's scales hold the moon's light. So: a rod, a bucket, a cat called Biscuit, and a whole island of water to fish.

Then come back five summers later. Every island once kept a tidelight that sang to the Moonfins, and one by one they went dark. Sail from Port Merrow's harbour to Ember Rock's hot springs and the ice of Whalebone Skerry, help each keeper with a problem (usually a fishy one), and light them up again.

And who keeps leaving lanterns burning just ahead of you?

A minute of sea air.

Trailer coming soon

▸ Fish everything

Ponds and brooks, rock pools and reefs, hot springs, holes in the ice and the open sea. Every fish keeps its own hours, and some only bite when the tide, the weather or the moon is right. Cast, wait for the nibble, strike, and reel in without snapping the line. Then fill in the journal, from the Sunny Bluegill (who looks like it got into the paints) to the Lantern Angler.

Small islands, lots to do, no rush.

Nine islandsEach with its own people, fish, shops, music and wildlife. A harbour town, a fen on stilts, a reef, hot springs, ice.
Quests across the seaClues, unmarked finds, puzzles and areas that open up, plus things that only happen at dawn, at low tide or on an aurora night.
The KittiwakeGrandpa's old boat grows with you, from a little sloop to one that crosses reefs, ice and steam. Paint her, change her sail, fly your own flag.
Friends and gossipHearts, gifts and heart scenes, and a journal that remembers who loves what (and who told you).
Days, nights and weatherRain, fog and aurora. The lanterns come on at dusk, and some fish only come out after dark.
