The girl the sea gave back
(Book)

"A standalone from the Sky in the deep, following Halvard (a character from SKY) ten years later" -- author's answer to reader's question on Goodreads.

Tova lives amongst the Svell, the people who found her washed ashore as a child and use her for her gift as a Truthtongue, but when two neighboring clans bury their age-old blood feud and join together as one, her world is dangerously close to collapse.

Tova lives among the Svell, the people who found her washed ashore as a child and use her for her gift as a Truthtongue. The sacred symbols and staves inked over every inch of her skin mark her as one who can cast the rune stones and see into the future. When two neighboring clans bury their age-old blood feud and join together as one, her world is dangerously close to collapse. Tova casts the stones and forsees the destruction of the Svell-- and that her own path is interwoven with that of Halvard, the Nādhir chieftain. -- adapted from jacket
