Samantha Marie Ramsden has three brothers. Craig, John and Matt. When tragedy strikes their family, Craig takes on the task of becoming his siblings legal guardian. It's hard enough being someone's guardian, but when you've only recently entered adulthood yourself it's almost impossible to know where to draw the line between sibling and 'parent'. This is made even harder on him when Sam starts to get close to a long time friend, Jason. It looks like their friendship could turn into something more. An idea that Craig has never been too happy with. Spanning six years, My Heart is Yours explores family, friendship, love and much more. As well as asking the question: Would you defy family for love?
