This syntactic proposal is interesting, well-motivated and presented in a logical and clear structure. It opens up fruitful opportunities for further work on the interface to semantics, which has also concerned itself with many of the phenomena touched upon here. The book starts off with a large data section which aggregates and complements previously reported judgments on the composition of the left periphery in English. For this part alone, the volume is a must read for any linguist interested in phenomena of the left periphery. The author meticulously records disagreements and variation with regard to the reported judgments, which can lead to new research into syntactic variation and cross-linguistic studies.
