The first book in The Infernal Devices series, Clockwork Angel is a great book for lovers of the Mortal Instruments series as this serves as a prequel series.

Trapped in their house and forced to improve an unique ability she never knew she had, Tessa is rescued by a mysterious young man called Will Herondale. Now dragged into a new world with weird beings, Tessa is determined to find her brother but soon learns that this new world may be more dangerous than she first thought.
