Quick Silver - Novel by Callie Hart

Quicksilver is a 2024 romantasy novel by British author Callie Hart, the first in her Fae & Alchemy trilogy. 

Plot: In the desert city of Zilvaren, ruled by the immortal Queen Madra, 24-year-old Saeris Fane survives by stealing water from royal reservoirs. She conceals an ability to manipulate metal. After guards catch her and drag her before the queen's captain for execution, Saeris accidentally pulls an ancient sword from a platform, an act that awakens a dormant portal made of quicksilver. A warrior called Kingfisher steps through and carries the wounded Saeris back with him.

She wakes in Yvelia, a frozen realm of the Fae, where she discovers she is an Alchemist, one of the rare few who can manipulate quicksilver and reopen portals between worlds. Kingfisher's stepfather, King Belikon, intends to exploit this power in his war against Malcolm, the vampire king ruling a neighboring realm.[6] Through an accidental magical oath, Saeris binds herself to Kingfisher, forcing them to work together forging relics that allow safe passage through the portals. What begins as mutual antagonism shifts toward romance as Saeris uncovers secrets about the war and about Kingfisher himself.

Personal Commentary: This novel entitled: Quicksilver belongs to a genre that I do not usually read. It takes the reader into a world quite unfamiliar to me and hence provided me with new learning of this kind of genre of novels.
