You may find Pages good enough (I think it handles layout better than Word IIRC). I only mentioned this because I had to take over a long complex project report with many wrapped images which was driving a collaborator literally insane in Word (every slight edit and a butterfly effect chaotic cascade of images fluttering all over the place), we forced it into submission clunkily in OpenOffice. This was as I say even when understanding the object anchoring system in Word intimately, visualising anchors and using optimal anchoring strategies. The other problem I remember from doing this in Word was you couldn’t add auto-figure numbers you could reference in wrapped images, not sure if that absurd limitation was ever fixed…
Indesign is like the Roll-Royce of layout systems, but you’ll have to switch into a DTP mentality for layout…
