Her Rebel Heart - Alison Stuart

The first time they met, she tried to kill him... Deliverance Felton has been left to defend her home, Kinton Lacy Castle in a time of civil war. She can shoot and wield a sword as well as any man and anything she needs to know about siege warfare she has learned from a book...but no book can prepare her for what is to come. Everything Captain Luke Collyer knows about siege warfare - and women - he has learned from experience. When he is sent by Sir John Felton to defend Kinton Lacy Castle against the Royalists, he will be up against a formidable force. He had not reckoned on that force being Sir John's daughter, Deliverance. Deliverance will not give up her command lightly and Luke will have to face a challenge to his authority as fierce as the cavalier foe outside the walls. As betrayal surfaces, they must learn to trust each other and uncover the traitor within the castle walls before it is too late for the castle... or their hearts.
