Meg, Jo, Beth, and Amy have grown up together in Orchard House with their friend Laurie next door, and now it’s time for them to go out and find their places in the big wide world, to do the great and marvellous things they’ve dreamed of and discover their ‘castles in the air’. They each find themselves tested, and fall in love, but when tragedy strikes they find their best comfort is in each other, and home.
