Good for you. The book you ought to buy is "The Turbine Pilot's Flight Manual" by Gergory N. Brown and Mark J. Holt.
The book is billed on the back as 'Everything a pilot is expected to know when transitioning to a turbine-powered aircraft'.
It is an exceptionally well written and clear book with chapters on:
Turbine Engine and Propellor Systems
Turbine Aircraft Power Systems
Major Aircraft Systems
Dedicated Aircraft Systems
Limitations
Normal Procedures
Emergency and Abnormal Procedures
Performance
Weight and Balance
Airplane, Handling, Service and Maintenance
Navigation, Communication, and Electronic Flight Control Systems
Hazard Avoidance Systems
Operational Information
Weather Considerations for Turbine Pilots
It is a very practical book (A4 softback) and is little use for examination style study. A bonus is that it is geared more for the transition to turboprops rather than turbojets.
In your position you won't regret buying this book!
Good luck.
