Girl Who Grew Wings by Anna Waterworth Paperback

In the citadel of Appollis, the Gods bestow single gifts on a

chosen few.

Icari has always known she's a Healer, while her twin sister,

Sephie, is cast as an Embalmer, despite showing early promise as

an Alchemist - a secret the sisters keep to themselves for possessing

two skills is punishable by death.

While Sephie learns how to wrap the dead, Icari eases the suffering

of others, including a charismatic enemy prisoner called Caszeil.

And it's to Caszeil that Icari turns when demons rise up from

the Underworld and kidnap her sister. With his help, perhaps

she can rescue Sephie. Even if this means growing wings - and flying

in the face of the devil himself . . .
