Title: Intuitive introduction, lacks rigor
Review: This is a fairly friendly, intuitive introduction to non-linearity, with an emphasis on bifurcations. There is a very brief discussion of fractals. It is probably most suitable for a 3rd or 4th year course. The level of mathematical rigor is a bit low, which will make the book easier for engineers and physicists but may leave mathematicians unprepared for a more advanced course.
