In Time For You is two charming compelling romances in one love story. Karlsen gives the reader two heroines and two heroes to fall in love with. When Emily and Electra, two sisters are both swept back to medieval England, the love of Electra's life, Roger must try to find a way back to save them. Finding a way back isn't the only problem, Roger is French. England at that time was at war with France. If he's caught, he will be taken as a prisoner or killed out right.
Roger does find a passage through time and while he is attempting to save the love of his life while avoiding capture on enemy soil, dear, techie oriented, thoroughly modern Emily is falling in love herself. She's found the man of her dreams in a medieval knight.
As with all of Karlsen's time travel romances, the love stories are richly brought to life against a wonderfully drawn medieval setting and terrific support cast of characters. I highly recommend this book. It helps to have read the previous three but this is a stand alone and can be read without having read the others.
