Long ago I saw a book on the AMS (American Mathematical Society) or the MAA (Mathematical Association of America) bookstore website that would do geometry following the Erlangen program.

In the introduction, the authors indicated that a second book would be written about non-Euclidean geometry, and I then decided to wait until this second book was written.

Now I was thinking about buying the book but I cannot find it any more.

I remember it was written by two authors — one I think from the University of Texas and I think it was published in 2009.Does anyone recognise this book?

Update 01/10/2017I found the book I was looking for ( but I do think gave some wrong hints)

The book I was looking for was:

Continuous Symmetry, from Euclid to Klein

By Barker and Home, American Mathematical Society 2007, (mbk-47)

ISBN 987 0 8218 9300 3

(No part two yet , but hope it will come some time)

Thanks for all other suggestions and sorry for all wrong hints

Maybe it’s this pair of books, no.1 and no.2, by Vaughn Climenhaga (who seems to be from the University of Houston). They were authored in 2008 and 2009 resp. with Yakov Pesin.

Same author also just released another book (that seems to fit the description) with Anatole Katok called *From Groups to Geometry and Back* which is based on a course taught in 2009.
