Linnea is a born and bred Swede but spends as much time as possible in Cape Town, South Africa. This is mainly due to Cape Town’s extraordinary scenery, wildlife, and atmosphere (in other words, because Cape Town is heaven on earth.) That being said, Sweden’s majestic forests forever hold a special place in her heart. Linnea spends as much time as she can close to the ocean collecting sea shells or in the park admiring puppies.
